FIELD: agriculture.SUBSTANCE: invention relates to the field of agriculture and land recultivation. In the method a mixed compost is used produced from the bark of fir-tree, larch and birch which is applied on the surface of toxic wastes in an amount of from 25 to 30% of the total mass. After laying, the mixing is carried out by disking to improve the conditions of establishment and survival of plants and to ensure a high biological activity of the substrate. The layer of mixed compost laid on the surface of the tailing storage facility with toxic wastes of mineral processing, disked at a depth of 5-10 cm and mixed with wastes, then seeds of legume-cereal mixture are sown, and heavy metals are bound by organic matter carbon and their main amount is immobilised up to non-hazardous limits. The area for recultivation of toxic wastes is contoured around the perimeter with the water-permeable boards and drainage grooves to speed up the discharge of storm water.EFFECT: method enables to reduce the negative impact of mineral processing wastes on the environment objects and to ensure the effective protection of the environment from industrial pollution.3 cl, 4 dwg, 4 ex |
