Leaching - Mining Fundamentals
The leaching process in mining is carried out either as heap leaching or insitu leaching. Precious metals such as gold are extracted from their ores by a cyanide or ozone leaching process. Radioactive metals, such as uranium are extracted by the process of acid leaching.

Leaching (metallurgy) - Wikipedia
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is ...
