FIELD: metal mining by leaching. SUBSTANCE: method includes separation of crushed ore for leaching by its separation into group by size classes and pouring into pile. Novelty consists in that in separation of ore into groups by size classes, finely divided ore fraction and coarse fraction with substandard content of useful components are removed. Ore is poured into pile by layers with group of same size class located in one layer. Each overlying layer is formed of ore whose particle size is smaller than that in underlying layer. EFFECT: higher efficiency.
