What Are Tailings

Tailings consist of ground rock and process effluents that are generated in a mine processing plant Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings This process of product extraction is never 100% efficient nor is it possible to reclaim all
