The project has received approval from the Federal Minister of Environment and Climate Change on the recommendation of the Joint Assessment Committee, comprised of representatives from the Impact Assessment Agency of Canada and the Cree Nation Government; The Corporation is working to obtain similar approval under the Qubec environmental assessment process. To ensure the highest lithium quality and yield, we precisely target impurities and selectively precipitate the lithium forms most valuable to a project. Spodumene Lithium. We are designing our Carolina Lithium project, located in Gaston County, North Carolina, to be a fully-integrated site. Our UHP RO minimizes brine from tough industrial wastewaters and delivers the highest freshwater recovery in the industry. The processing almost always begins with concentration via crushing, grinding and froth flotation, followed by drying in a rotary dryer to produce a dried lithium concentrate. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). With slight grinding the excess acid could be reduced to 15%. It offers a direct sulfate and acid-free method to produce battery-grade lithium hydroxide monohydrate from spodumene concentrates.

Spodumene Concentrate is a lithium aluminum silicate with the chemical formula Li [AlSi 2 O 6 ]. Spodumene ore naturally occurs in the crystal structure of monoclinic alpha form (-form). Todays global lithium production comes mainly from hard rock deposits such as Tianqi Lithiums (SZSE:002466) Greenbushes mine in Australia, or brine deposits such as SQMs Salar de Atacama in Chile. Next a hybrid microwave heating set up was designed which applied three SiC sticks to absorb microwave energy and conventionally heat the spodumene sample. Ganfeng and Mineral Resources have plans to build a lithium-hydroxide plant with a nameplate capacity of 20,000-25,000 tpy in Kalgoorlie for the production of battery-grade lithium hydroxide compounds using the Mount Marion output. However, the value of the concentrates produced at hard-rock mines is on average US$6,250/t LCE lower than that of the lithium chemical products produced at brine operations. Piloting of the thermal conversion of the ore from -spodumene to -spodumene (See Critical Elements press release dated April 13, 2017). 3 0 obj These prices are provided in various currencies and based on despatch or delivery at a number of relevant locations, e.g. We believe we are uniquely positioned to deliver lithium hydroxide as a key resource to the market. 0000008808 00000 n Spodumene is a gemstone and its price fluctuates depending on the demand. Critical Elements aspires to become a large, responsible supplier of lithium to the flourishing electric vehicle and energy storage system industries. At this time, the majority of the leading hard rock lithium producers are not vertically integrated with their own conversion operations, placing those with conversion capabilities at a high advantage when it comes to gaining market share and maintaining higher profit margins in the lithium-ion battery industry. Lithium is produced mainly from brine and hard-rock deposits, both of which make distinct products of differing value.
