As a result, producers focused on developing brine deposits, while spodumene sources remained largely ignored. Forward-looking information is based on assumptions management believes to be reasonable at the time such statements are made. This can be derived from either of the lithium chemicals that can be produced from the processing of concentrates described above. We offer comprehensive modelling, piloting, and full-scale solutions that convert DLE outputs into battery-grade inputs. 0000003361 00000 n The goal of the acid roasting step is to allow the lithium to be extracted from the mixture as water-soluble lithium sulfate, which is amenable to leaching. The plant will convert spodumene, a hard-rock mineral mined for lithium, into 60,000 tonnes of lithium carbonate equivalent (LCE) per year in the city of Yichang, in central China's Hubei. In addition to temperature, the effects of acid dosage and roasting time were investigated. In the production of lithium compounds from spodumene concentrate, calcination is utilized to carry out two separate steps in the process: decrepitation and acid roasting. %PDF-1.5 There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. 0000019024 00000 n Albemarle and Ganfeng turn spodumene concentrate from Australia into lithium hydroxide in China. By. This INNSpired article provides information which was sourced by INN, written according to INN's editorial standards, in order to help investors learn more about the company. A direct-fired kiln utilizes direct contact between the material and process gas to thermally process the ore. NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES. FEECO is a leader in custom thermal processing equipment. 0 Known for its high lithium content, spodumene is the most widely exploited mineral source of lithium. Lithium was also recently recognized in the, Critical Mineral Resources of the United StatesEconomic and Environmental Geology and Prospects for Future Supply . Unlike lithium products derived from brine operations, hard rock spodumene deposits produce a concentrate that must be further processed into either lithium hydroxide or lithium carbonate for use in lithium-ion batteries. Concentrate used for pilot plant testing was provided from sample taken from Critical Elements Rose and Rose South zones. // ]]> stated earlier in the project that the first drill holes sample appeared to be about 20m thick and estimated to contain around 35% spodumene. In addition, the pilot plant produced battery grade lithium hydroxide . However, the value of the concentrates produced at hard-rock mines is on average US$6,250 per tonne lithium carbonate equivalent (LCE) lower than that of the lithium chemical products produced at brine operations. FEECO is a leader in advanced thermal processing and agglomeration process solutions and custom equipment.
