    Hence, the gross value of the ore would have to be greater than $80/t (equating to a gold grade of 2 g/t) in order to justify the mill. 1.3. Heap Leaching Configurations. Configurations of heap leaching available include dynamic heaps, permanent singlelift and multilift heaps, and valleyfill heaps. 1.3.1. Permanent Heaps

  • In situ leach Wikipedia

    Insitu leaching (ISL), also called insitu recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state.

    Silver Heap Leaching 2000 TPD. A silver agglomerationheap leaching operation is located near Tombstone, Ariz. Two types of materials are mined: old waste material that was used for mine backfill and ore adjacent to the waste material. The waste material is mined with frontend loaders to expose the ore.

    In 2011 leaching, both heap leaching and insitu leaching, produced 3.4 million metric tons of copper, 22 percent of world production. The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although heap leaching is a low costprocess, it normally has recovery rates of 6070%.
