METHOD OF CLEANING QUARTZ SANDS FROM IRON

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to hydrometallurgical treatment from iron of quartz sands of various degree of iron content and can be used in mining, metallurgical, glass, ceramic, chemical and electrical industries, in production of construction materials. Proposed method comprises removing iron from quartz sands in blocks at sand deposit or in a vat version with wetting and irrigating sands with a culture solution, containing facultative anaerobic Saccharomyces, Oidium, Bacillus, Bacterium. Achieved degree of purification of sands from iron is 85-99 %.;EFFECT: technical result is higher efficiency of removing iron of quartz sands of various degree of iron content using a simple technique in environmentally safe conditions.; 8 cl, 1 tbl, 2 ex
