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

Dense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.Web

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

Hydrocyclone Coal Washers. The hydrocyclone, like the dense-medium cyclone, was developed by the Dutch State Mines (DSM). Essentially, it is a cylindro-conical unit with an included apex angle of up to 120°, much greater than the included apex angle of the dense-medium cyclone. The hydrocyclone also has a longer vortex finder than does …Web
