Nemaska Lithium (TSX:NMX,OTCQX:NMKEF) recently shipped several potential customers lithium hydroxide samples produced from its Shawinigan Phase 1 plant facility using concentrate from its Whabouchi mine in Quebec. The reaction between the sulphuric acid and the spodumene is presented below. While lithium can be derived from a variety of sources, one source of lithium looks to be making a resurgence in the effort to meet future lithium demands: spodumene. Accordingly, readers should not place undue reliance on forward-looking information. Spodumene is a gemstone and its price fluctuates depending on the demand. While generally higher on the cost curve than brine operations, spodumene concentrate is converted into battery-grade lithium hydroxide which trades at around $16,000 per tonne ex-works in China . Facilitated by calcination, decrepitation expands the spodumenes crystal structure by about 30%, ultimately allowing the otherwise chemically inert ore to react with sulfuric acid., In processing spodumene concentrate, calcination causes decrepitation at temperatures between 1075 1100 C. Temperature control during calcination is crucial to the success of the process; if temperatures are allowed to approach anywhere near 1400 C, undesirable formations between the alpha spodumene and other silicates can occur (referred to as eutectics).. In addition, the pilot plant produced battery grade lithium hydroxide with 99% purity. Australia-based AVZ Minerals, part owner of the project, recently announced their findings of a 295.05m thick intersection of spodumene bearing pegmatite a highly promising discovery.

In addition to its high concentration of lithium, lithium extraction from spodumene also typically offers lower capital costs and a shorter time from discovery to production in comparison to brine operations. However, exploding demand for lithium is calling for more lithium-bearing resources than ever before. During process development, particular attention is paid to potential by-products such as tantalum, niobium or cesium, and also to industrial minerals such as quartz and feldspar which may be recovered during mineral concentration, leaching and purification. The conventional commercial process requires high-temperature calcination to transform -spodumene into. Microwave acid roasting of -spodumene is a promising method with less energy consumption. Lithium chemical processing capabilities are key to capturing higher margins for lithium producers. Lithium hydroxide is mainly prepared by alkaline method, that is, it is prepared by the roasting of spodumene and calcium hydroxide, and some of them are prepared by the so-called sodium carbonate pressure method, that is, the solution containing lithium is prepared first, and then lime is added to the solution to prepare lithium hydroxide. endstream endobj 305 0 obj <> endobj 306 0 obj <> endobj 307 0 obj <>stream INN does not endorse or recommend the business, products, services or securities of any company profiled. //L{bvULV>$|/9}x'=MzL)_6C) OIY#J"Y>l;s|{8ngG=G3|XVN:ah Deliveries should start between July 2022 and June 2023. 4 0 obj /E !5$X b)R1!J":8cmIFo~dYq^"I;ZoBe'k(d&rd+E et;=I,6q/M2Z6 4oB_cv(e{CQ*eqW)ieV5^)83,aNS8c+((((%10yKc9sN|`>W1+W'9lH.u{y{y{y{y{yI$[6w GH-}v N* ~ The completion and successful production run of the projects Dense Media Separation (DMS) mini pilot plant was also recently announced.
