Research on the Application of Mo-Ni ore Pre-discarding Tailings by Small-diameter Hydrocyclone
For the Mo-Ni ore that mineral composition is complex,and the grade is relatively low,the flotations effect is not good in advance for enrichment,because of the influence of fine grained level gangue minerals.The small diameter hydrocyclone were used to pre-discard tailings,with the best pulp density and feed pressure,the rate of throwing is the 30%,and then the flotation obtained a good beneficiation index.The crude ore that contains Mo 2.04 %,Ni 1.87 %,through the closed-circuit test won a concentrate that the grade of Mo is 8.94 % and the recovery is 91.86 %,the grade of Ni is 6.75 % and the recovery is 86.79 %.Compared with the single flotation process,it improved the flotation effect and the enrichment ratio of Mo Ni,and realized the efficient enrichment of Mo-Ni.
