Lithium Mining and Extraction

Lithium is found in two main types of deposits: hard-rock mines (typically spodumene) and brine deposits (salt lakes). In hard-rock mining, the lithium-containing ore is extracted from the ground and then processed to separate the lithium. In brine extraction, the lithium-rich brine is pumped from underground and left to evaporate in large ponds. The resulting concentrate is then further processed to produce lithium carbonate or lithium hydroxide, which are used in batteries. Both methods come with their own environmental considerations, including water usage and land disturbance.

Nickel Mining and Processing

Nickel is usually mined from sulfide or laterite deposits. Sulfide deposits are often mined underground, while laterite deposits are often mined using open-pit methods. The extracted ore undergoes a process of smelting and refining. Sulfide ores are usually smelted to produce a nickel matte, which is then further refined. Laterite ores often require more complex processing, such as high-pressure acid leaching, to extract the nickel. Again, the environmental impacts of nickel mining include land use changes and potential water pollution, making careful management vital.
