· Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it’s important to reshape tailings management and accelerate the positive change.

· Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s. Rocks that contained both gold and arsenic were crushed and then spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand-like substance is known as tailings.
