METHOD FOR LOW-COST TREATMENT AND DISPOSAL OF MINING WASTES Russian patent published in 2016 - IPC C02F9/04 C02F1/28 B01J20/24 C02F103/10 

FIELD: mining.

SUBSTANCE: invention can be used in the mining industry for the purification and recycling of metal-bearing weakly acidic pit water in a bog-mountainous terrain. For carrying out the process, after neutralization with an alkaline reagent haul water fed to the natural geochemical barrier in the form of peat deposits fen. Contained in water salts of metals accumulate natural sorbent and precipitated in natural geochemical barrier as an insoluble organo-mineral complex. Resulting permanent or temporary watercourse fed purified according to the terrain in the direction of the stream or river. Fen peat deposits as a natural sorbent used in view of the sorption capacity of peat fen calculated by cation exchange capacity of peat with respect to the cation exchange capacity of the metal ions contained in the quarry waters.

EFFECT: method provides an efficient and low-cost technologies pit water cleaning helps prevent the intense migration of the metal salts in natural systems.
