Use of dry grinding process to increase the leaching

2021-5-1  In the wet grinding process, 10 mg of gold powder was mixed with different amounts of Fe 2 O 3, then 1 mL of deionized water was added, and the grinding time was 5 min. The gold ore leaching experiment was performed in a 200 mL solution containing 10 mM Cu(II), 1.0 M NH 3 and 0.2 M thiosulfate. The mixing speed and temperature were the same as those in the gold powder leaching experiment. In the dry grinding process, 50 g of roasted gold

How Does A CIP Gold Processing Plant Work?

2021-3-18  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.
