In addition to fine grinding dump material, the feasibility study indicated that additional grinding of the main plant CIL tails could increase gold recovery. However, operation after startup showed that the additional gold recovered from the CIL tails was not economic.

Introduction to Mineral Processing

The concentrate, which is now approximately 30% Cu and 0.35% Mo, is pumped to the molybdenum plant where the molybdenum disulfide is separated from the copper sulfide. Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals to float.
