Abstract
This Bureau of Mines study was conducted to determine the sulfur reduction potential attainable when washing fine-size coal on a spiral concentrator. Crushed samples of Middle Kittanning and bakerstown bed coals washed on the spiral provided pyritic sulfur reductions of up to 90 percent for the plus 200-mesh material. Pyritic sulfur reductions on the minus 200-mesh material seldom exceeded 30 percent; consequently, this material would require further treatment. The capacity of the spiral was 2 tph per unit when washing 14-mesh by 0 coal. The ability to remove pyrite combined with the higher-than-expected capacity makes the spiral worthy of consideration as a rougher-cleaner in new fine-coal desulfurization circuits.
