As an example, for certain type of ore bodies, many copper mines have switched to a leaching process for recovery of the copper. This process involves percolating a chemical solution through stacked "heaps" of material to dissolve the contained copper. Depending on the nature of the ore body, the heap can consist of crushed or uncrushed ore.
Contact ustons of copper ore to recover 441,000 metric tons of copper. Hydrometallurgical Processing The leaching process extracts copper by dissolution in sulfuric acid. This method is suitable for low-grade copper ore bodies for which customary mining operations would be uneconomical, as well as for the leaching of remnant ores from abandon mines.
