摘要: During beneficiation of coal at the mining area Tula, Russia, huge volumes wastes with considerable residual pyrite content are produced. These that usually disposed without specific care in environment active sources mine drainage generation which severely contaminates soils, surface- and groundwater endangers ecosystems area. In present paper a complete environmental characterization research is carried out order to determine characteristics wastes, establish their acid potential, leachability bio-availability several hazardous constituents predict impacts disposal sites. Based on this data as well process parameters practices, an evaluation desulphurization technologies out. Experimental studies reveal these considered permanent therefore cause extensive contamination addition, due technological constraints potential situ low. Desulphurization higher only if applied framework integrated waste management scheme.
