Tailings. Tailings are a fine-grained residue, mainly consisting of gangue minerals that remain after the separation of valuable minerals and metals from their ore in a processing facility. Tailings are deposited in the vicinity of the mine and are therefore pumped together with process water to large ponds, known as tailings.

Environmental impacts of metal mining Vplivi kovinskih . - RMZ

Abstract: The impact of mining and processing of metal ores on the environment is de- scribed. Mines produce large amounts of waste, because ore is only a small fraction of the total volume of mined material. Mining is a process that begins with exploration for and discovery of mineral deposits and continues through ore.
