Dense-medium beneficiation of fine coal revisited

this reason, dense-medium beneficiation of fine coal was reconsidered. Motivation In past years, much of South Africa's export coal was produced from the No. 2 Seam. The fine fraction from this seam is relatively easy to beneficiate in spirals. In future years, however, a large proportion of coal will be mined from the No. 4 Seam.

The world's largest coal producers rely on our beneficiation spirals for the treatment of fine coal streams. Most Australian coal washeries employ one or more banks of our signature LD7 and LD7RC spirals. In the USA we've installed over 1,000 coal spiral starts and treat in excess of 18,000,000 tonnes of coal annually across the region.

Gravity Spiral Concentrator Working Principle

The Primary Spirals Separator. Feed from the splitter screen passes down into the gravity feed pump hopper and from there it is pumped to the static distributor above six triplex type primary spirals. As the pulp passes down these spirals; separaration of particles occurs according to specific gravity and the heavier minerals progress to the inner profile while lighter minerals are forced
