DEVELOPMENT OF TECHNOLOGICAL AND REAGENT REGIMES FOR OBTAINING PYRITE CONCENTRATE FROM CURRENT TAILINGS OF MOF-1 OF ALMALYK MINING AND METALLURGICAL COMPLEX

Abstract

The rational use of mineral resources and the reduction of industrial waste are among the most important tasks of modern mining and metallurgical production. Large volumes of flotation tailings accumulated at mining and processing enterprises contain significant amounts of valuable components that can be reprocessed using modern beneficiation technologies. One such example is the current tailings of the MOF-1 (Mining and Ore Processing Factory No.1) of Almalyk Mining and Metallurgical Combine (AGMK), which contain sulfide minerals, particularly pyrite. Pyrite concentrates are widely used in sulfuric acid production and metallurgical processes. The purpose of this research is to develop technological and reagent regimes for obtaining pyrite concentrate from current tailings of MOF-1. The study examines the mineralogical composition of the tailings, flotation conditions, reagent selection, and optimization of technological parameters. Experimental results demonstrate that appropriate reagent regimes and flotation conditions significantly improve pyrite recovery from tailings. The obtained pyrite concentrate meets industrial requirements for further chemical processing. The research contributes to improving resource efficiency, reducing environmental impact, and increasing the economic value of mining waste through secondary processing.
