  • Silver Gold Recovery Flotation Process

    Silver Gold Recovery Flotation Process. Previous Next it might be profitable to make an iron concentrate containing the gold. If the gold and silver can only be brought up in the desired concentrate by contaminating it with unwanted mineral, the mode of procedure must be determined by the economics of the case. Dry grinding of the oreOre Dilution & Recovery in Mining,Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably
