Leaching (metallurgy)

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 the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings pared to pyrometallurgy leaching is easier to perform, requires less energy and ...
