Gold Cyanidation Heap Leaching cnlitereagent

2019-10-12  Type of Cyanide Heap Leaching. The industrial cyanide heap leaching method can be divided into two types, one is short-term heap leaching and the other is long-term heap leaching. In the short-term heap leaching method, the ore is usually crushed to less than 20 mm. When processing gold-bearing quartz veins, it is often crushed to less than 6 mm.
