Optimal reagent regime for flotation of molybdenum ore from the Bugdaya deposit

It is highly important this day to study new-generation flotation agents for developing a new processing technology for ore from the Bugdaya deposit since the traditional reagents fail to provide high concentration efficiency. The research findings on enrichment of molybdenum-bearing ore are analyzed, and the possibility of using new-generation flotation reagents to improve flotation efficiency is proved. The material composition of ore from the Bugdaya deposit is investigated using the advanced research methods (mineralogical, chemical and photocolorimetric analyses). The lab-scale flotation tests have achieved the main goal of proving the feasibility to increase molybdenum recovery in rougher flotation concentrate using modern Clariant’s collectors and frothers. Enhancement of flotation efficiency of finely disseminated molybdenite from the Bugdaya deposit with a new reagent—Hostaflot LET, and with replacement of pine oil by Flotonol D-14 is demonstrated. The optimal consumptions of the tested flotation reagents are determined. The rougher flotation mode with production of rough concentrate at maximum molybdenum recovery is optimized. The efficiency of the proposed technological approach is proved by the comparison of molybdenum recoveries at the level of 95.26% in the proposed method and at the level of 88–90% in the current technology. The resultant rough molybdenum concentrate can be brought to the standard quality with the appropriate finishing mode. The present research findings can be of use when the Bugdaya deposit containing huge molybdenum reserves is put into operation.

Keywords: flotation, molybdenum ore, molybdenum extraction, flotation reagents, reagent mode.
