What are Tailings Society for Mining, Metallurgy

Tailings are a by product of mining. After ore containing an economically recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed tailings. Typically, mill tailings range from sand to silt
