Weir Minerals, global leader in the provision of mill circuit technology, dewatering solutions and services, has launched the new Multiflo® MudfloTM hydraulic submersible slurry pump. Engineered for abrasive applications and large particle handling, the Multiflo® MudfloTM pump features a hydraulically driven wet-end specifically designed to efficiently and safely reprocess and relocate tailings ponds, maintain water retention dams and manage slimes and sludge ponds.
The innovative solution combines the Warman® MGS pump-end, Multiflo® CB32 hydraulic cutters and ESCO® excavation teeth to provide efficient pumping of highly charged and abrasive slurries.
Weir Minerals' unique Ultrachrome® A05 chrome alloy impeller ensures high wear resistance and the specially engineered suction strainer minimises the risk of clogging by preventing large solids & debris from entering the pump. Drawing on decades of Warman® pump design experience, the Multiflo® Mudflo™ pump is capable of pumping between 150 and 1,200m3/h, up to 82m head.
The Multiflo® CB32 hydraulic cutters feature market-leading ESCO® Ultralok® tooth system to prevent premature breakage, avoid tooth loss and protect the integral locking system to ensure the continuous operation of the pump.
Engineered by the Weir Minerals dewatering pump experts in Australia, it is available for global customers from July 2021.
“The Multiflo brand is synonymous with high quality and long-lasting equipment. In designing the Mudflo pump, our dewatering experts drew from the very best Multiflo, Warman and ESCO technology and used advanced hydraulics to create an innovative and cost-effective new solution for mine dredging applications,” Cameron Murphy, Director of Dewatering Weir Minerals APAC said.
Weir Minerals understands that success is built from enduring partnerships based on close collaboration and a mutual commitment to safety and technical excellence.
“It is not uncommon for sites to use a combination of pumps, shovels, excavators and trucks for dredging applications. When one of our long-time partners in Indonesia contacted us about developing a custom solution for the slurry build-up in their sumps, we knew we could provide a better solution,” Geoff Way, Weir Minerals Dewatering Specialist said.
“We’re problem solvers. We considered our customer’s pain points and engineered a new solution to efficiently and safely manage their site processes,” he said.
The Multiflo® MudfloTM pump can also be retrofitted to competitor OEM equipment; the quick-hitch plate attachment ensures convenient installation and removal from hydraulic excavators.
The Multiflo® Mudflo™ pump can be assembled on land, eliminating the safety risks associated with assembling pumps over water. Furthermore, the new hydraulic hose management system reduces the risk of hose entanglement and trip hazards, all the while providing a reliable hose bend radius to ensure smooth oil flow.

New Report Identifies Major Carbon Reduction Opportunities in Global Mining
New analysis lays out the scale of the mining industry’s energy use and identifies ways it can be reduced using currently available technologies Materials such as copper, lithium and nickel play an essential role in the technologies like electric vehicles and renewables that will help the world meet its decarbonisation targets As demand for these metals increases, the mining industry must itself become more efficient and environmentally sustainable The global mining industry must move away from legacy systems and processes if it is to meet the challenge of decarbonisation, according to a new report released today which calculates mining’s share of global energy consumption and identifies ways the industry can aid the transition to net zero emissions needed to limit temperatures in line with the Paris Agreement. The report, commissioned by the Weir Group plc, analyses mine energy data from over 40 published studies to give a comprehensive understanding of where energy is consumed in mining and minerals processing. It shows that the total amount of power used by the mining industry – which plays an essential role providing the metals used at the heart of the modern economy – is equal to c.3.5% of global energy use. The metals produced by mining are critical for enabling the global transition to low-carbon infrastructure. But without action, energy use in mining itself is set to trend higher in the coming years as demand increases for metals like copper, nickel and zinc. The report suggests there are technologies available today that could make a significant difference to this trend. For example, it highlights that comminution – i.e. crushing and grinding processes – is the single biggest user of energy at mine sites, typically accounting for 25% of mining’s final energy consumption. This is equivalent to the power used by 221 million typical UK homes, or c.1% of total consumption globally. Comminution is therefore a natural target for the most impactful energy savings opportunities. Small improvements in comminution technologies can lead to relatively large savings in both energy consumption and greenhouse gas emissions. For example, a 5% incremental improvement in energy efficiency across comminution could result in greenhouse gas emissions reductions of more than 30m tonnes of CO2-e. The replacement of traditional comminution equipment with new grinding technology also reduces indirect emissions in the mining value chain, for example by removing the need for the manufacture of emission-intensive steel grinding balls. Of the remaining energy consumption by the mining industry, diesel in varied forms of mobile equipment accounts for 46%, electricity in mining (ventilation) 15% and “other electricity” 14%. Other significant opportunities identified by the report for reducing mining’s energy consumption include optimisation, big data and artificial intelligence. In addition, if zero emissions energy sources are deployed for mining equipment – e.g., renewable energy, energy storage and alternative fuels – then the industry may well be able to achieve zero emissions, leaving a relatively small role for offsets and carbon credits to play. The report comes as the mining industry is under ever-greater pressure to produce essential minerals that support some of the biggest global structural trends, from population growth to urbanisation and decarbonisation. Copper, nickel, steel and lithium are core components of electricity transmission and storage, electric vehicles and renewable energy infrastructure. The move to a decarbonised economy will result in increased primary consumption of these mined commodities, even after factoring for recycling, so it is important that mining itself becomes more sustainable. Download the independent Mining Energy Consumption 2021 report here: www.energysavingsinmining.com Commenting, Weir Group Chief Executive Jon Stanton said: “The mining industry is central to economic development globally, with critical minerals enabling the low-carbon transition required in the rest of the economy. But the environment in which it will operate in future will be very different from the past, requiring comprehensive change and investment. In short: mining needs to become more sustainable and efficient if it is to provide essential resources the world needs for decarbonisation while reducing its own environmental impact.This report is an important contribution to that debate which we hope will spark thoughtful conversations around the world on the way forward.” Alison Keogh, Chief Executive of the Coalition for Energy Efficient Comminution, said: “This report highlights both a challenge and an opportunity to revitalize cross-industry discussion and actions on decarbonisation and ESG solutions. We invite industry leaders to actively contribute and collaborate through mining-vendor-research partnerships and share knowledge. Together, we can accelerate improved energy, emissions and water footprint across industry faster.” Ricardo Garib, Weir Minerals Divisional President commented: “Weir Minerals is focused on making mining more efficient and sustainable by leading technology change in the industry. Our Enduron HPGRs are increasingly replacing conventional milling systems in comminution (crushing, screening and grinding) circuits because of their substantially lower energy consumption, finer rock reduction requiring less water downstream and potential for significant total cost of ownership reductions.” Stuart Hayton, Managing Director of Weir Minerals Netherlands, where the Enduron® HPGRs are designed and manufactured, added: “Not only do Enduron HPGRs require as much as 40% less energy than traditional alternatives, their wearable components last much longer and the maintenance time required to replace worn out parts is significantly lower. The estimated carbon saving of each Enduron HPGR in operation is equivalent to taking more than 3,600 petrol fuelled cars off the roads each year.” Notes: The report quantifies energy use in five commodities: copper, gold, iron ore, nickel and lithium. Bringing together mine energy use data from more than 40 published studies (each of which references dozens more studies) from 2007 to 2020 into a single narrative, the report aims to build a more comprehensive understanding of energy use in the mining industry. Using the current production rates of the commodities in question, and the energy intensities for each of the commodities, a total of 1,68 EJ/a (1,680,000,000,000,000,000 joules per year) has been calculated. This is approximately 0.5% of total final energy consumption globally. Published information indicates that the entire mining industry consumes approximately 12 EJ per year – or 3.5% of total final energy consumption globally. Assuming that present trends continue, there will be 250m electric vehicles on the road by 2030. To meet this demand, production of cobalt, lithium, graphite and nickel will need to be scaled up significantly. Current projections show that the current rate of decarbonisation globally is far below what is required to meet the goals of the Paris Agreement. A sustained decarbonisation rate of up to 7% per year, year on year should be sufficient to achieve the goal of a temperature increase of well below 2°C by 2100. For the mining industry, there are multiple ways to achieve decarbonisation including energy efficiency and fuel/energy switching. Many of these opportunities are starting to be explored by both the mining companies and the mining services providers, who see decarbonisation and energy reduction as a key way to reduce exposure to the risks of climate change.

Oil Search Considering Merging with Santos
Santos, an Australian oil firm, announced its plan to combine with Oil Search Limited. Santos proposed a non-binding indicative merger last month with the goal of making the two companies the regional energy champions. The proposed merged entity has a market capitalization of A$22 billion (K56 billion), putting it among the top 20 ASX-listed companies and the top 20 global oil and gas companies. This means, among other things, that the merger will have a diverse portfolio of high-quality, long-life assets spanning Australia and Papua New Guinea, a solid balance sheet with ample cash to support expansion choices, and an investment-grade credit rating. The merger plan, if approved, would be conducted through a Scheme of Arrangement in which Oil Search shareholders would receive 0.589 new Santos shares for each Oil Search share held, according to Santos in a market disclosure to the Australian Stock Exchange. Following the scheme's acceptance, Oil Search shareholders would control 37% of the combined company, while Santos shareholders would own 63%. Based on Santos' closing price on June 24, 2021, the ownership ratio suggested a transaction price of A$4.25 (10.92) per Oil Search share. This was a 12.3% premium to the Oil Search closing price of A$3.78 (K9.72) on June 24, 2021, and a 9.8% premium to the Mubadala block trade selling price of A$3865. (K9.92). Kevin Gallagher, managing director and chief executive officer of Santos, said the merger will bring more alignment to PNG, allowing for the development of important projects such as Papua LNG, as well as the creation of new employment and support for the local economy. Santos, according to Gallagher, has proposed a true merger in which ownership of the combined firm is based on proportionate contribution and value. “The strategic rationale for a merger is clear and offers superior value to Oil Search shareholders rather than continuing on a standalone basis. “Santos continues to believe that the Merger Proposal represents an extremely attractive opportunity to deliver compelling value accretion to both Santos and Oil Search shareholders.” Oil Search stated in its ASX market update that it is open to receiving and engaging with any proposal that is in the best interests of its shareholders. While the company's board of directors agrees with Santos that combining the two firms makes strategic sense, the conditions must be fair to the company's shareholders, which the terms proposed by Santos are not. Despite Santos shareholders holding 70% more shares than Oil Search shareholders, Oil Search maintains that the proposed conditions provide just a 6.8% premium based on Friday's closing share prices for Oil Search and Santos. According to the firm, no such proposal has been made at this time. Reference: Post-Courier (21 July 2021). "Oil Search Open To Merger with Santos".

Study Says Sweet Potato Growers Have Received Significant Insights into Customers Buying Habits
In Papua New Guinea (PNG), sweet potato (kaukau) growers have received significant insight into customer buying habits, which is assisting them in identifying new market possibilities. The recent market analysis, which was supported by the Papua New Guinea-Australia Partnership and conducted by the Australian Centre for International Agricultural Research, revealed that an increasing number of consumers in Port Moresby prefer to buy fresh produce from supermarkets, citing convenience and safety as reasons. While this trend may result in fewer consumers at conventional farmer markets, PNG and Australian experts believe it may open up new marketplaces for rural people. “Farmers are looking for stable markets where they can receive more consistent prices for better-quality produce,” said Professor Philip Brown from Central Queensland University (CQU), who is leading the research project. “The research shows that consumer behaviour is likely to support an expansion in the supermarket sector in large urban centres and this is positive news for the farmers. This could allow commercial focused farmers to secure more stable market access.” The study of 353 customers was conducted as part of ACIAR-funded sweet potato research sponsored by CQU and the PNG National Agriculture Research Institute (NARI), which aims to improve sweet potato value chains by increasing the quality of harvested roots. Sweet potato quality and production are improving, resulting in increasing supplies to retailers eager to provide better fresh produce. “The project, with support from the Fresh Produce Development Agency and NARI, is helping farmers to build their business skills and connect with emerging supermarket opportunities,” said Professor Brown. Kirt Hainzer, a CQU researcher who collaborated on the survey alongside NARI researchers, said it was the first study to look at customer behaviour and see what role stores may play in the development of PNG's commercial sweet potato sector. “The research sought to better understand and compare how consumers buy staples from open markets and supermarkets and to explore the preferences for purchasing staple foods as supermarkets increase the availability of convenience staples like rice,” said Hainzer. “Although expanding formal sales represents a huge step forward in developing a commercial sweet potato industry, continued research on consumer preferences and the market for fresh produce will help better understand trends in staple food purchasing and what market opportunities exist for growers.” With over a hundred kinds of sweet potato in the nation, NARI economist Raywin Ovah said the study sought to find out which of these customers preferred. “Not all the varieties are preferred from a consumer point of view. There are only a few that consumers want to be based on the taste or health properties and that is what we want to also find out. Farmers can be provided with that information, so they produce those varieties that the market wants.” One of five initiatives under the Transformative Agriculture and Enterprise Development Program is a project to increase commercial sweet potato production and commercialization in the PNG highlands. The ACIAR program, which is funded by Australia in collaboration with the government of Papua New Guinea, aims to improve the livelihoods of rural men and women through private sector-led development, increased agricultural productivity and quality, and the development of individual and institutional capacity.

Garry: MRA Evaluating K50 Billion Worth of Investments
According to managing director Jerry Garry, the Mineral Resources Authority is evaluating more than K50 billion in investments in the country. Wafi-Golpu, Frieda River, and Woodlark are among them. “We are also looking at the Central Lime and Cement,” he said. “If that project comes on-stream, it will be one of the first industrial mines ever built in the country.” Garry was speaking at a Port Moresby consultation session on the Mine and Works (Safety and Health) Bill 2021. PNG, he added, was home to some of the world's largest mines. “We have grown from strength to strength,” he said. “If you compare the Bank of PNG statistics, the mining sector alone, in terms of production, has exported over K17 billion in 2020 and 2019. “So it’s a huge industry that we are trying to regulate and manage.” Garry expressed gratitude to the industry for making safety a primary priority. “They have been taking health and safety at the workplaces very seriously,” he said. “We must not only consider (the workers) and the environment but also people living around the (areas) we operate in. “And if we are using any hazards, we must also take responsibility.” The newest mining methods in Wafi-Golpu, known as block cave mining, are one of the new things to expect, according to Garry. “New mining hazards will come with this new mining method,” he said.
