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.

Dec 4, 2020Ore processing comprises the following steps: The first step is about crushing as well as grinding the gold ore. Experts add process water to make a slurry (a semi-liquid mixture). Then, experts add lime to the ore, whereas they mix cyanide solution with the slurry to filter the precious metals into the solution.

The process began with roasting (burning) the ore for six weeks in the open air. This reduced the sulfur content but spewed sulfur dioxide into the air. Then the ores were smelted in a furnace. The gold, silver and copper settled to the bottom of the liquid. Workers skimmed the worthless slag from the surface of the matte, the amalgam of minerals.
