|- A principle of the staged transition to the sustainable
environmentally pure nature management for mining enterprises was suggested.
The first stage is deactivation of flows of solid waste, emissions and
discharges by binding environmentally dangerous components into the environmentally
compatible products. The second stage is their immobilization in lithosphere
aimed at creating conditions for further transformation of unclaimed raw
materials into industrial raw materials of postponed use.
- There were suggested the ways for using materials based on iron-containing hardening mineral dispersions for highly effective purification of liquid radioactive waste (purification level is not less than 99%). They depend on concentration of radioactive component in the initial solution: by low concentrations there is expedient purification in dynamic regime in flow-type columns, by high concentrations - under static conditions of sorption at fine sorbent fractions (less than 0.2 mm).
- Strategy for remediation of lands under Subarctic conditions was developed. It is based on the use of heterogeneous porous materials on the basis of hydromicas as substrate components. They are used to oxidize the hard-to-oxidize pollution due to the creation of heterogeneous structure of oxygen potential. It provides for formation of aerobic and anoxic conditions for development of biocoenosis and conditions to destruct pollution under the temperature lower than 100C. At the same time, an oxygen source (for example, peroxides of alkaline-earth metals) is introduced into the medium being purified. Self-maintenance of destructive processes is caused by low heat conduction of granules - less than 0.07 kal/g?? by the ratio between external and internal surface of granules from 1:20 to 1:100, and 90% of pores are of radius from 500 to 1000A.
