The Method of Recycling and Utilization of Technogenic Anhydrite Obtained from Sulfur-Containing Flue Gases

Abstract

There are presented the results of investigations of some properties of technogenic anhydrite i.e. calcite anhydrite obtained when capturing sulfur-containing gas at the MMC "Norilsk Nickel" OJSC; the compositions of stowing solutions using technogenic anhydrite to fill mine voids at the same enterprise are developed as well. The results of these investigations may be of interest to professionals working at the enterprises of metallurgy, where the production of metals is accompanied by emission of sulfur-containing gases, power plants using sulfur-containing fuels and emitting sulfur dioxide with the flue gases, enterprises of mining industry, where it is possible to reduce the cost of stowing mixtures by replacing the natural anhydrite by the technogenic one.
