PHOSPHORUS ONDIRISINDEGI PHOSPHATE SHIKIZATYNYN AGGLOMERATIONS

Abstract

The depletion of reserves of high-quality ores, i.e. the deterioration of the quality of raw materials, has the consequence that the work of phosphoric production with good technical and economic indicators is possible only with the organization of stable modes of operation of furnace units at high capacities, and this is provided only in the case of appropriate preparation of raw materials. All phosphate raw materials to feed in the ore-thermal unit shall be subjected to a preliminary calcination, with the aim of maximum reduction of the energy costs for secondary processes taking place in the furnace bath. The article deals with the essence of agglomeration of phosphate raw materials and process parameters. The optimal variant of preliminary calcination of phosphorite raw materials is offered. Chemical and physico-chemical analysis of agglomerate with the use of boiler milk obtained during electrothermal processing of agglomerated phosphate raw materials was carried out.
