Copper-separating process of high-sulfur copper ore containing higher silicate minerals of speckstone and like

The invention relates to a copper-separating process of high-sulfur copper ore containing higher silicate minerals of speckstone and the like. The process comprises the following steps of: using solvent naphtha No. 200 and aerofloat sodium as a collector, oil No. 2 as a foaming agent and sodium sulf...

description The invention relates to a copper-separating process of high-sulfur copper ore containing higher silicate minerals of speckstone and the like. The process comprises the following steps of: using solvent naphtha No. 200 and aerofloat sodium as a collector, oil No. 2 as a foaming agent and sodium sulfite as an inhibitor; carrying out bulk floatation on chalcopyrite and easily-floating silicate minerals; adding aluminum sulfate and ferrous sulfate for inhibiting the obtained copper-silicon mixed concentrate ; and re-separating and recovering the chalcopyrite by using a shaker. By the provided copper-separating process, copper ore in ore can be effectively recovered, the easily-floating silicate minerals are floated in the copper-separating process, and the influence of the silicate minerals of speckstone and the like on the subsequent floatation and recovery of sulfurous iron ore is eliminated.
