MAQOLA ANNOTATSIYASI

Currently flotation waste - copper concentrating mill (CCM) Almalyk mining and metallurgical combine (AMMK) and metallurgical slags and floooded and also phosphogyps – waste for all producers of phosphorus fertilizers is on volume one of the first places among the by-products of industry and these wastes are one thousand hectares of land suitable to agriculture. The problem of handling large – capacity sulphate production waste-phosphogyps, which is formed up to 1.6 tons when processing 1 ton of raw materials, is complex. The global annual output of phosphogyps is more than 150 million tons, while Uzbekistan accounts for about 3 million tons. Currently, our Republic has accumulated about 80 million tons of phosphogyps. Therefore, the use of these wastes in the production of building materials is relevant not only from the point of view of resource conservation, but also from the point of view of environmental protection. In this regard, one of the options for using them in the production of building materials is proposed. In particular, the possibility of obtaining glass for construction purposes based on phosphogyps and flotation waste from a copper processing plant has been established. Some physical and chemical properties have been studied, and the crystal phases of crystallized glasses have also been determined. Glasses and glass crystallized materials formation on the base of phosphogyps and flotation tails of a copper factory has been investigated. Certain physical - chemical properties and crystallizability of the received glasses has been studied. The main crystal phases of crystallized glasses have been examined by thermal, microscopic end X-ray analyses.
