ICMM About tailings

About tailings. Tailings is a common by-product of the metals and minerals recovery process. It usually takes the form of a liquid slurry made of fine metal or mineral particles and water – created when mined ore is crushed and finely ground in a milling process. From the mill, the tailings is typically pumped to storage facilities which are ...

About Tailings – Global Tailings Review

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.
