| Popis: | The work is devoted to an important environmental and economic problem: the enrichment formed wastes recycling and brown coal processing. If pyrite sulfur (pyrites) is extracted from high-sulfur coal before it is burned, the negative impact on the environment is reduced (sulfur dioxide emissions reduction into atmospheric air) and, as a result, environmental payments, as well as the possibility of obtaining sulfuric acid from pyrite. Waste coal preparation plants can be used in the building materials production (ceramics, cements, concrete aggregates), in the hydraulic structures construction, as well as with the purpose of improving the soil fertility in agriculture. |
