Leaching uses less electricity than traditional mining and does not produce waste gases. Copper ores are treated with and dissolved in dilute sulfuric acid, producing copper sulfate. Electrolysis is then used to extract the copper. Certain bacteria can also be used to dissolve ores and form copper sulfate. Phytomining uses plants to absorb metals

 · However, while the use of a wet process significantly improves the surface activity, the presence of water also increases the risk of cobalt leaching. This become increasingly significant as the number of sequential wet blast processes increases (ie, the time that the carbide is wet, for example when edge radiusing and then surface preparation is taking place).

Leaching. Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis.
