Aug 21, 2020 · An Overview of Commercial Lithium Production. Most lithium is commercially produced from either the extraction of lithium-containing salts from underground brine reservoirs or the mining of lithium-containing rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Copper Mining and Production Processes Explained

The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting. This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine.
