— Jig washing systems can treat both large and small coal in a single unit. Over the years, jig washers have shown a significantly improved performance, particularly in cleaning small coal. One of the most notable developments in this area has been the Batac jig, which in some forms, is claimed to be capable of washing coal down to 3 mm.

— We use tools like jigs, spirals, and shaking tables for this job. They use gravity to organize particles by how heavy they are and their specific gravity. This technique shines when dealing with bigger chunks and is a go-to method for mineral sands and gold. Also, this method works really well for heavy minerals like tin, tungsten, and chromite.
