During mining and mineral processing, technogenically disturbed lands are generated and require reclamation. This paper considers the feasibility of producing an effective ameliorant for reclaiming disturbed lands at mining facilities using complex organomineral ameliorants derived from chemical industry waste containing cellulose nitrates. An approach to producing such complex organomineral ameliorants is substantiated. The resulting ameliorants are shown to meet the chemical-composition requirements of GOST R 54534-2011 for use in the technical and bio-logical stages of reclamation and to possess additional beneficial agrochemical properties. In a pot experiment with oat (Avena sativa) and meadow bluegrass (Poa pratensis), the application of complex organomineral ameliorants produced pronounced positive increases in above-ground plant biomass relative to background models with sand alone: 58.8-104.9 % for oat and 245.5-1721.8 % for meadow bluegrass. Compared with the background model using livestock waste (cattle manure), biomass increases were 5.2-11.6 % for oat and 290.9-413.8 % for meadow bluegrass. A positive effect on the root systems of both species was also observed. The proposed ameliorants based on the waste in question are shown to be suitable for reclamation of mining facilities, and the utilization technology offers a positive economic effect.
