gold ore grinding sizing

gold mining process development denver mineral engineersas pyrites. in a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation. advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
