Heap Leach Mining Process

Gold heap leaching process means transfer the raw ore to the prepared yard or directly stock on the waste rock or low-grade ore then use cyanide leaching liquid to spray or infiltrate and the ore reacts with the cyanide leaching liquid. After several recycling of leaching liquid and repeat spray the leaching liquid can be collected.
