Abstract

Nowadays, the exploitation of the Pervomayske deposit is in the northern direction. The large metasomatic bodies of ferruginous quartzites are manifested in the productive strata in the northern part of deposit. The metasomatic bodies of ferruginous quartzites influence technological parameters of the iron ore concentrate.This situation determines the purpose of this investigation. The mineral composition, genesis and technological parameters of riebeсkite ferruginous quartzites of the Pervomayske deposit productive strata are studied. The metasomatically changed ferruginous quartzites and features of their mineralogical zoning are examined mineralogically. The zones of riebeсkitization are substracted within the boundaries of metasomatic bodies.The mineral composition, the structural and texture of riebeсkite ferruginous quartzites are studied. The technological research for enrichment of riebeсkite ferruginous quartzites is conducted. Results of the mineral composition, the structure and the texture investigation, conditions of genesis of riebeсkite ferruginous quartzites of riebeсkite ferruginous quartzites are given. Generalized regularities in changing of ore technological parameters (iron content in concentrate composition, concentrate ratio, iron recovery in the concentrate, iron losses in mine tailings) in the metasomatic bodies section of deposit's productive strata are presented. The authors studied the influence of sodium metasomatism on technological parameters of riebeсkite ferruginous quartzites The results of mineralogical and technological studies of authors have been used as the basis for compiling mineralogical and technological maps for the deposit that are utilized for operation and future mining, for elaborating schemes of optimal iron ores blending before conveying them to concentration plants with the purpose of increasing the iron ore concentrate quality and decreasing iron losses in concentration wastes. Originality consists in detailed carrying out of mineralogical research of riebeсkite ferruginous quartzites of the Pervomayske deposit. Further, these results are used in technological tests for enrichment of riebeckite ferruginous quartzites. It is necessary to take into consideration the obtained regularities of the variability for the technological parameters while specificating the mineralogical and technological ores classification and the mineralogical and technological mapping of the Pervomayske deposit.
