Enrichment of Molybdenum and Fluorite by

The molybdenum and fluorite were obtained in different phases with the flotation of fluorite ore containing molybdenum obtained from Karaama ğaradere-Keban-Elazığ district in Turkey. It has been found that the original ore contains 1.08 % Mo, 0.05 %Cu, 1.20 % Pb, 1.12 % Zn and 12.0 % F. It was determined that molybdenum and fluorite could not be enriched in different phases with satisfactory yields by flotation of original ore at the defined size. Thus, the ore was sulfurized before the flotation. Concentrates containing molybdenum and the other concentrates containing fluorite were collected with fairly high yields in different phases by the flotation of the sulfurized ore. In the optimum flotation conditions, the Mo, Pb, Cu and Zn were obtained over 95 % yields and approximately 6 % fluorite passed into concentrate phase. Mo and Cu containing phase were enriched with high yield by selective flotation of concentrate obtained from the concentrate. On the other hand, most of Pb and Zn remained in tailing. In order to gain molybdenum, the appropriate concentrate was obtained by this process with hydrometallurgical method. It was also determined that the trace amounts of Ta, Nb and V in ore were collected in the concentrate phase.
