Gold Ore Flotation Machine With High Recovery Rate
As 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.
