What are Tailings

Tailings are a byproduct of mining. After ore containing an economicallyrecoverable 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 ...

SPECIAL REPORT: Why is mining still so dangerous ...

May 20, 2019 · The biggest obstacle to mine safety – the reason so many miners die at work – is profit. It is entirely possible to process mine tailings safely, but it costs more. Mines can be reinforced to prevent collapse, but this takes time. Safety is expensive, and would make some marginal mines uneconomic.

Guidance about tailings storage

Tailing storage facilities (TSFs) are reservoirs that store mine tailings, which is finegrained waste material in suspension that is discharged from an ore processing plant or coal preparation plant. Inappropriate storage of tailings can lead to safety, health and environmental hazards.
