Experimental Study on Flotation Process of A Greisen-Type Tantalum-Niobium Ore in Jiangxi Province
According to the characteristics of a Yun-quartz tantalum niobium ore in Jiangxi Province,the flotation process is designed,and the flotation fineness,concentration,open circuit,closed circuit,rough concentrate cleaning,and comprehensive tailings recovery are studied.The results show that through the flotation process scheme,a hydrometallurgical tantalum niobium coarse concentrate with a raw ore yield of 0.03%,Ta2O5 grade of 16.99%,Nb2O5 grade of 25.66%,Ta2O5 recovery rate of 38.99%,and Nb2O5 recovery rate of 58.89%could be obtained.The tailings are subjected to comprehensive recovery tests to obtain iron lithium mica concentrate with a raw ore yield of 26.01%,Li2O grade of 2.30%,and Rb2O grade of 0.75%,as well as quartz feldspar concentrate with a raw ore yield of 63.45%,K2O+Na2O content of 4.4%,and Fe2O3 content of 0.07%.This provides a reference for subsequent mining production or selection of beneficiation processes for similar ores.
