Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines.
Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and Travancore in India.
