WEBINTRODUCTION Coal gold agglomeration (CGA) is a new concept in gold processing. It involves the recovery of oleophilic (oilloving) gold grains by causing them to adhere selectively to the surfaces of coal oil agglomerates. Under optimum conditions very high recoveries of gold. can be achieved. The agglomerates are recycled to build up gold .
WEBThis study aimed to investigate the applicability of coaloil gold agglomeration (CGA) assisted flotation to recover gold from a refractory ore. The ore with the grade of 25 g/t was tested with the CGAflotation process in six different size fractions from 38 to 300 urn using different collector types and dosages. In addition, the flotation without CGA was .
