METHOD OF FLOTATION CONCENTRATION OF RARE-EARTH METAL AND TIN ORES |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to concentration of rare-earth metal and tin ores. Proposed method comprises primary flotation by oxyhydril collector to produce crude concentrate, concentrate thickening and directing it to cleaner floatation. Liquid bacteria Bacillus mucilaginosus in amount of 10-20 ml per 1l of concentrate is added to thickened crude concentrate pulp to be held out for at least 3 days and directed to cleaner flotation to be conducted at pH of at least 6. ^ EFFECT: higher yield of valuable components. ^ 2 tbl |
