HARD ROCK MINING Lithium extracted by "hard rock" comes from the minerals hosted in Pegmatites. These metal-enriched deposits form during the final crystallization of the earth's magma as intrusive rocks that can measure anywhere from just a few centimeters to hundreds of meters. Within Pegmatites is the lithium-bearing mineral, Spodumene. The hard rock method extracts lithium directly from Pegmatites with common surface mining techniques. Mineralized Pegmatites are crushed, milled, and separated according to ore mineral identification. SNOW LAKE 4 LITHIUM LITHIUM FAQ VS Lithium found in Spodumene can be processed into lithium carbonate or lithium hydroxide - the compound preferred by EV battery manufacturers. Hard rock uses traditional mining techniques that require significantly less water and energy at a lower cost. WHERE IS LITHIUM FOUND? HOW IS LITHIUM EXTRACTED? WHAT ARE THE BENEFITS AND IMPACTS OF LITHIUM? BRINE MINING Brine mining sources the mineral from accumulations of saline groundwater known as lithium brine deposits that have strong concentrations of dissolved lithium. Only select regions in the world contain viable brines for mining purposes. The brine mining method pumps brine to the surface of the deposit to be evaporated in a succession of ponds. Each transfer to a new pond achieves higher purity until the lithium can be fully extracted and processed. Brine mining requires a diversion of water and its long-term environmental effects remain ambiguous. It is a multiyear process to extract and can only be successful in limited weather conditions, including sufficient sunshine and limited rain. Its processing abilities are less flexible as brine only initially produces lithium carbonate, which must be extended to lithium hydroxide at an additional cost.
