Chromite an overview ScienceDirect Topics
Mining of chromite is carried out by open-pit and underground mining. Whereas open-pit mining is generally applied to podiform deposits, underground mining is applied to stratiform deposits. Chromite ore is mined in over 20 countries, but about 80% of production originates from four countries: South Africa, India, Kazakhstan, and Turkey ( Kleynhans The history of chromite exploration in Sukinda valley started way back in 1949.
