FIELD: mining.
SUBSTANCE: claimed process comprises piling the initial material and leaching of useful components with the application of leaching agents. Note here that said initial clay-bearing material is piling in inclined layers, said initial material alternating with fibrous capillary-porous material layer. Said fibrous capillary-porous material layer is reinforced. First, said fibrous capillary-porous material layer is shaped to lumps. This fibrous capillary-porous material layer is impregnated prior to piling with concentrated leaching agent while the pile at leaching is irrigated with water. Said fibrous capillary-porous material layer is made from leaching agents.
EFFECT: lower labour input.
