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.
