| Abstract: |
| The occurrence of lithium in a refractory lithium mine in Mongolia is complicated. The lithium-containing minerals mainly include zinnwaldite, lepidolite and lithium-containing muscovite, and their lithium occupation rates are 48.11%, 36.15% and 6.94% respectively. The lithium-containing muscovite has a low grade of Li2O, which easily affects the grade of lithium concentrate. The particle size distribution of target minerals such as zinnwaldite, lepidolite and lithium-containing muscovite in the ore have uneven particle size distribution, and contains chlorite, kaolinite and other easily slimed minerals. During grinding operations, it is necessary to ensure that the target minerals achieve suitable particle size and monomer dissociation, while avoiding the impact of fine mud on the pulp environment. Aiming at this complex and refractory lepidolite ore, through determining reasonable grinding fineness, desliming treatment before flotation, and using inhibitor sodium hexametaphosphate and efficient collector BK426 in the flotation process, lithium-containing minerals can be efficiently separated under neutral conditions, and the recovery rate of lithium concentrate can be significantly improved. Under the condition that the Li2O content of the raw ore is 0.75%, the Li2O grade of lithium concentrate is 3.74% and the recovery rate is 75.93%. The research results can provide useful reference for the development and utilization of lepidolite resources of the same type. |
