Systematic processing of iron-ore waste in mining regions

详细

Management of the stepwise processing of iron-ore waste in mining regions ensures rational resource utilization by introducing waste-free and low-waste technologies, with subsequent conversion of the reclaimed land to recreation areas. A procedure that may be used by operational enterprises has been developed, including the sequence of operational steps, charts for tailings recovery and preparation of the equipment, and schedules. The steps run in parallel and include waste processing, recultivation, and the solicitation and selection of proposals for the creation of recreation areas. Waste processing and land reclamation proceed while the enterprise is in operation. The recreation areas go into operation after the enterprise has closed. Management of the stepwise processing of iron-ore waste at enterprises that have closed involves the development of funding sources for waste processing and land reclamation: this will include sale of the existing resources (buildings and equipment) and approaches to outside investors, including the state. With insufficient funding, some of the iron-ore waste may be used as construction materials or filler in the reclamation program. Management of the stepwise processing of iron-ore waste for ongoing projects includes periodic monitoring of the waste generation and damage to the ground cover. Existing technologies for waste utilization and recultivation of the affected land are applied. Periodic monitoring prevents environmental damage. Recreation areas are created while the enterprise is functioning, and go into use after it has closed. On the basis of these management procedures, proposals are made for the introduction of waste-free and low-waste technologies in the Tashtagol region of Kemerovo Oblast. Such technologies are simulated by means of SciLab software. For purposes of selection, the proposals are ranked.
