The worlds insatiable demand for high purity lithium products to feed the booming battery market is prompting renewed interest in the exploration and development of spodumene deposits, with a number of projects underway. %PDF-1.4 % document.write(theDate.getFullYear()) We chose North Carolina as the home of our corporate headquarters due to its proximity to our proposed Carolina Lithium project as well as the electric vehicle supply chain. Traditionally lithium hydroxide was produced from lithium carbonate, resulting in a high degree of price correlation between the two chemicals in the market. Spodumene has a theoretical Li2O content of 8.03%. We also offer a unique testing facility to aid in process development. Saltworks process harvests lithium hydroxide solids that reach or exceed battery-grade specifications. This leads to cracking of the particles and their dispersion to smaller particles. 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. Saltworks offers solutions for every step, including comprehensive concentrate, refine, and convert packages. Various process data points can be tested to find the optimal combination for lithium recovery. Since the -spodumene ore is not sensitive to products of combustion, a direct-fired rotary kiln is used to process the material in this setting. , part owner of the project, recently announced their findings of a 295.05m thick intersection of spodumene bearing pegmatite a highly promising discovery. 0000015922 00000 n The process is also environmentally sustainable as the residues are inert and easily neutralized. endstream endobj 308 0 obj <>stream The organic phase comprises a quaternary ammonium chloride and a hydrophobic phenol in a diluent.
