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.Web

The primary disadvantage of a heavy media process is the ancillary equipment that must be installed to support the operation of the separator (Fig. 11). A typical circuit requires that the clean coal and refuse products pass over drain-and-rinse screens to wash the media from the surfaces of the products and to dewater the particles.Web
