Tailings are the waste products from mining – mining waste. During mining, machinery and chemicals are used to grind up rock into a fine sand to extract minerals and metals from the rock, along with large amounts of water, often in countries prone to drought. Everything that isn’t useful at the end of this process is waste.

Tailings is a common by-product of the process of extracting valuable minerals and metals from mined ore. They usually take the form of a liquid slurry made of fine mineral particles, created as mined ore is crushed, ground and processed. Effective tailings management is integral to the safe and sustainable production of metals and minerals.

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
