Proedimiento to the total concentration of metal sulfides to facilitate environmentally correct closure of underground and Open Pit Mines

摘要

A process that separates the remaining Tailings or Tailings in Sulphide Flotation to obtain a minimum proportion of Tailings acid Generator (Tailings acid) and a large proportion of consumers (Tailings Tailings acid neutral).The process comprises the steps of: (a) separate most of sulfides in the Tailings concentration by froth Flotation, preferably at a pH close to neutral or slightly acid, with Collectors and frothers Conventional, so gather most of the M Ineral acid Generator in a Small Volume, called u00f4relave u00e1cidou00f6,And could generate a large volume of consumer of Mineral acid, called u00f4relave neutrou00f6; (b) in the case of underground MiningStore called u00f4relave u00e1cidou00f6 In deeper areas of the Galleries Chimneys or Underground Mine and cover it with a large volume of the u00f4relave neutrou00f6 to prevent the access of oxygen and its corresponding oxidation; (e) in the case of Open Pit Mining Or,The so-called u00f4relave u00e1cidou00f6 store in the deepest area of the Open Pit and cover it with a large volume of the u00f4relave neutrou00f6 to prevent the access of oxygen and Water, and its corresponding oxidation; and (d) store in the area called u00f4relave remaining without neutrou00f6 Another condition that preserve their physical stability in view of that, will not generate Acid In short,Medium or long term, and can be replanted directly or with a small coverage of Organic soil.
