Experimental Study of Flotation in A Spodumene Mine in Australia
An experimental study on the flotation of spodumene from a lithium polymetallic ore sample in Australia was carried out.The grade of Li2O in the ore is 1.51%,and the gangue minerals are mainly quartz,mica and albite.The experimental results show that,considering that the fineness of the ore is about 75%of-0.074mm,a new collector Q is used to obtain a spodumene concentrate with a grade of 6.52%Li2O and a recovery rate of 89.89%through the closed-circuit flotation process of pre-removal of mica+one coarse,one fine and one sweeping,and the spodumene mineral is fully enriched in the ore.At the same time,the extracted mica product has high purity and can be used as an additional product of this program.After sorting,the useful components Ta2O5 were obtained with a grade of 0.0985%and a recovery rate of 69.87%,and a Nb2O5 grade of 0.0337%and a recovery rate of 73.81%,which could provide suitable raw materials for the subsequent comprehensive recovery and utilization of tantalum-niobium.
