coal-oil-gold agglomeration [4-11] and the promising environmental and technical viabilities of the process  have raised the need for adoption of this method in small scale mining in Tanzania where the hazardous use of mercury is still dominant , and was the motiva- tion for doing this research
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the .
INTRODUCTION Coal gold agglomeration (CGA) is a new concept in gold processing It involves the recovery of oleophilic (oil-loving) gold grains by causing them to adhere selectively to the surfaces of coal oil agglomerat Under optimum conditions very high recoveries of gold can be achieved
