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. Battery manufacturers are still working on perfecting the right cathode chemistry for balancing power and performance with safety and stability. Lithium is extracted as a sulphate solution, which is purified prior to the manufacture of lithium carbonate or lithium hydroxide. 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. The high price per tonne for lithium hydroxide or lithium carbonate compared to spodumene concentrate can erode the low production cost advantage of hard rock producers, particularly when considering where the value chain is retained at the mine or offsite at the conversion facility.
