| Abstract: |
| Through the study of process mineralogy of a granite pegmatite type lithium pyroxene deposit in Africa, it was found that lithium in the deposit mainly exists in the form of spodumene and diopside feldspar. The mine has been in trial production using conventional gravity separation flotation process for many years, but has not achieved good beneficiation indicators. This experiment adopts the heavy medium flotation combined process and selects the combination collector LA+LB with good collection performance for mineral processing research. Under the condition of 1.31% Li2O grade in the original ore, heavy medium operation can obtain 4.05% Li2O grade and 27.82% recovery lithium feldspar concentrate, flotation operation can obtain 6.01% Li2O grade and 41.44% recovery lithium pyroxene concentrate, with a total Li2O recovery rate of 69.58%. Compared with a single flotation process, the heavy medium flotation combined process can obtain additional lithium feldspar concentrate, and the total recovery rate of Li2O is increased by 28.22%. |
