There will be two main types of waste: quartz sand and waste from the processing stage. Quartz sand. In the initial processing stage, we crush the rock into sand before it goes into a magnetic separator that extracts the high-grade material. The leftover material is a type of sand equivalent to a building aggregate already being mined nearby for use in various construction industries. Leach residue. The leaching stage produces a lithium-rich liquid which is the starting point for chemical processing (this is the final stage that produces the lithium hydroxide other saleable chemical by-products). This “leach liquor” needs to be purified, and the residue from that process becomes a non-toxic dry waste product. We are exploring opportunities to find commercial uses for this waste stream. Alternatively, being a benign material, it can be placed underground as backfill material.
