Dupont process

A heavy-liquid minerals separation process in which organic liquids of high specific gravity, known as parting liquids, are used. With sp gr 1.00 to 2.96 and very low viscosities, they serve ideally for the medium in the sink-and-float separation of solid materials. This process is used to clean run-of-mine anthracite, refuse banks, or mixtures of the two. The sizes of anthracite coal that can be cleaned are No. 1 buckwheat, and larger. This includes sizes up through broken.
