DMI-65® for arsenic removal Drinking water treatment plant (DWTP) filtration system for arsenic removal - Toquepala copper mine, Peru Removal of arsenic DMI-65 is a manganese dioxide (MnO2) infused media whose surface acts as a good oxidant and is effective in removing both arsenite and arsenate, as well as iron/arsenic complexes and precipitants. Iron and manganese buildup Build up of iron and manganese results in very high maintenance overheads, loss of production and potentially system failure. DMI-65® efficiently removes dissolved iron to the almost undetectable levels as low as 0.005mg/L and manganese to 0.001mg/L as well as particulate, effectively removing this risk. Reduced costs The total cost of the iron and manganese removal water filtration system is significantly less than...

Tivan progresses with fluorite mine in WA after critical minerals list addition Critical minerals company Tivan (ASX: TVN) has announced it will progress with plans to develop a fluorite mine in WA’s Kimberley region. Fluorite is used to produce fluorine, which the Federal Government added to Australia’s critical minerals list in December 2023. Tivan stated the Federal Government added fluorine to Australia’s critical minerals list in recognition of its role in the energy transition and lack of production in Australia. The company, which plans to mine fluorite in the Speewah region of the Kimberley, says fluorine can be utilised for chemical manufacturing and emerging sectors including...

4000 LTI-free days for Whitehaven’s Gunnedah CHPP Whitehaven Coal’s (ASX: WHC) Gunnedah coal handling and preparation plant (CHPP) recently achieved 4000 Lost Time Incident (LTI) free days, equivalent to about 11 years without a Lost Time Incident. Production superintendent Derek Welsh says this achievement is a testament to the strong leadership and safety processes that have been diligently maintained within the CHPP. “I strongly believe that this achievement is the result of a work culture based on hard work and commitment to teamwork,...

Australian Critical Minerals Prospectus released The Australian Critical Minerals Prospectus was today released by the Federal Government, showcasing 52 high-quality, investment-ready critical minerals projects. The Prospectus includes projects that are ripe for funding including mining, processing and value-adding opportunities across the critical minerals supply chain, all of which will create more employment for Australians. Federal Resources Minister Madeleine King says Australia’s critical minerals are key to the world’s energy transformation. “But we need to attract investment to get these minerals out of the ground, to process them here, to build the batteries, wind turbines and solar panels required make the switch to a lower carbon economy,” she...

Magnetic South donates defib to Dingo, Queensland Residents of Dingo, in central Queensland, are better protected in the case of an emergency thanks to the donation of a defibrillator by Magnetic South, which has been installed outside the township’s library. The donation was made as part of the launch of Magnetic South’s pre-construction Community Benefit Fund, which is now open and taking applications. Magnetic South communications manager Sharni Mancell says the Fund is designed to provide residents from the Dingo district with an opportunity to apply for grants of up to $2,000 to support programs and events that help create a strong, vibrant and healthy community. “Our priority is to...

A highly experienced team of graphite processing specialists from Metachem’s operational facility and staff have been assembled. All members have a track record in expandable graphite processing, with competence in maintenance, technical aspects and operational analysis. Commissioning of services areas...

Lake Johnston heritage survey completed A Cultural Heritage Survey has been completed at Rubix Resources (ASX:RB6) Lake Johnston project in WA. A survey team comprising of registered Native Title Holders, the Ngadju People, Terra Rosa Cultural Heritage Consultancy and Rubix staff has reviewed the sites of proposed new access tracks and drill holes. The survey approved the location of 30 holes for exploration activities with modifications that will authorise Rubix to avoid mature vegetation and to preserve the integrity of the local flora and fauna. The initial phase of exploration will largely use existing access tracks with proposed...

Battery anode testing a success at Graphite Bull Electrochemical work has demonstrated the suitability of graphite from Buxton Resources (ASX:BUX) Graphite Bull project in feed for lithium-ion battery anode manufacture. Since April 2023, graphite industry specialist ProGraphite in Germany has been managing mid and downstream testwork on Graphite Bull concentrate. Final results confirm that the uncoated purified spherical graphite (uPSG) made from the Graphite Bull concentrate is suitable for manufacture of lithium-ion battery anodes, yielding above average to good performance characteristics. Work involved constructing an anode and lithium-ion battery from Graphite Bull uPSG with subsequent electrochemical testwork including multiple charging and discharge tests to determine electrical capacity and durability characteristics. This...

Surefire Resources develops breakthrough vanadium extraction process Surefire Resources (ASX:SRN) has developed a breakthrough process of extracting vanadium directly from magnetite concentrate at its Victory Bore vanadium project in WA. After a 96-hour leach directly from magnetite concentrate, a vanadium extraction of 91% was achieved. Unexpectedly, an 88% titanium extraction was also recovered. The leach process was applied to pre-treated concentrate, allowing the leach process to effectively scavenge vanadium. This pre-leach treatment is Surefire’s intellectual property. In May 2023, Surefire appointed METS Engineering to undertake an assessment of potential recovery of a high purity vanadium oxide in liquid form, from which a clean high purity vanadium electrolyte could be produced for use in Australasia’s...

True North Copper and Glencore partner for Cloncurry product True North Copper (ASX:TNC) has signed binding offtake and toll-mining agreements with Glencore for its Cloncurry copper project (CCP) in Queensland. Under the agreements, Glencore will purchase 100% of copper concentrate from Cloncurry and process up to 1mtpa of Cloncurry ore at its Mount Isa smelter. True North will be entitled to claim 20% Queensland State royalty discount for all material processed through the smelter. The tolling agreement contains customary terms and conditions, including agreed tolling charge and agreed processes for assaying, weighing, sampling and moisture determination. True North managing director Marty Costello says the agreements...

Rio Tinto drives development of Gladstone solar farm Rio Tinto (ASX:RIO) has agreed to buy all electricity from the 1.1GW Upper Calliope solar farm for 25 years to provide renewable power to its Gladstone operations. This agreement will bring more renewable power to one of Australia’s most important industrial hubs and marks a step towards Rio’s climate goal of halving its global scope one and two carbon emissions this decade. If combined with more renewable power and suitable firming, transmission and industrial policy, it could also provide the core of a solution to repower Rio’s three Gladstone production assets — the Boyne aluminium smelter,...
