How Does A CIP Gold Processing Plant Work?

A reasonable grinding process is determined by the three most important factors: the hardness of the gold ore, the gold ore inlay, and the requirements for the particle size of the grinding product. The grinding process of the CIP gold processing plant is the same as that of the non-ferrous metal ore. There are also one and two stages of grinding.

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.
