Abstract:In gold recovering processes, coal gold agglomeration (CGA) is a novel process which has many advantages compared with conventional CIP/CIL, such as better environmental protection, lower operation and capital cost. The study on gold recovering from amalgamation tailings by CGA process showed that about 88% gold can be captured by coal oil agglomerates(COA) and the gross gold recovery is more than 85%. CGA process can be applied for extracting gold from hard(rock) ore, alluvial ore, and other gold bearing ores, which are difficult for cyanide processes because of high copper or arsenic content and difficult for gravity process because of small gold particle size, and certain refractory gold ores as well.

Key words: CGA process amalgamation tailings gold recovering
