Abstract: The current status of tantalumniobium ore dressing in a mine in Jiangxi is relatively simple,and it is difficult to achieve effective recovery of polymetallics.To solve this problem,a feasible reform guiding plan was proposed.By conditions experiments of the shaker,jigging and magnetic separation,the feasible joint process of magnetic separationgrovity separation and jiggingmagnetic separationgrovity separation were compared.According to the experiment results,the magnetic separationgravity separation combined closedcircuit test can obtain the following results:ZrO2 grade of 60.78% in zirconium concentrate,recovery rate is 88.83%;Nb2O5 grade of 42.09% in antimony concentrate,recovery rate is 46.08%;the Sn grade of 31.69% in tin concentrate,and the recovery rate is 49.31%.Under this condition,the comprehensive recovery of the multipurpose metal of the tantalumniobium ore can be realized.
