4 Factors Influence the Effect of Heap Leaching Method

In practice, the ore particles that have been crushed to 5 20 mm are sent to heap leached. If the content of ore fines -200 mesh exceeds 35%, the conventional heap leaching method will cause the surface of the ore heap to form a groove flow, thus reducing the leaching rate of gold. 2. Influence of the Leaching Solution
