Tailingsfo What are tailings? Their nature and productionIntroductionNature of tailingsProduction of tailingsTailings characteristicsTailings 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 reusable and expended processing reagents and chemicals.
