Investigation on Molybdenite Separation from a Complex Sulfide Ore
A Mo middling has been obtained through Cu-Mo bulk flotation. In order to further enrich molybdenite and separate pyrite form this middling. A series flotation tests were conducted to concentrate Mo. Important parameters including regrinding fineness, CaO dosage and cleaning flotation stages were optimized to enhance Mo enrichment. In addition, a close-circuit flotation test was conducted under optimum parameters and a Mo concentrate with 22.92% of Mo grade and 93.75% of Mo recovery was obtained, which satisfied the plant requirement.
