Improved grindability and gold liberation by microwave ...
· After microwave processing, the grindability of the ore was improved and the crushing strength and the Bond Work Index were reduced by 31˙2% and 18˙5%, respectively. In addition to the enhanced grindability, gold was released from the matrix of the host minerals at a coarser size, resulting in a significant increase in free gold recovery by gravity concentration.
