Beneficiation of South African chromite tailings using
The gravity separation process is the main beneficiation process used to recover chromite mineral. However, these conventional chromite processing techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75µm) leading to losses [1, 2]. Apart from that, separation of chromite from other associated ...

Coal Mining and Processing Methods
The first washing methods were imported from Europe, The "Chance" washer, in which the density differences between coal and mineral matter was exploited to clean raw coal was introduced in 1918. The Chance washer utilized sand and water as a medium. Today, the "heavy-media" process using magnetite is standard for coarse coal cleaning.
