Abstract
The Bureau of Mines conducted laboratory beneficiation tests on four samples of waste granite sludge to devise a method of recovering silicon carbide (sic). Froth flotation using creosote as a collector in an alkaline circuit resulted in concentrates containing over 91 pct sic from each of the samples. Recoveries ranged from 43.1 to 86.6 pct. Single-stage flotation of sample a using a column flotation cell produced a concentrate containing 92.0 pct sic with a recovery of 71.4 pct. Flotation using petroleum sulfonate as a collector in an acid circuit resulted in a concentrate containing 95 pct sic from one of the waste granite products with a recovery of 97.5 pct.
