Abstract

PURPOSE: To perform separation of copper and lead extremely effectively by allowing ore containing liquid to contact with gaseous carbonic acid in separation of copper and lead from the mixed ore concentrate.
CONSTITUTION: Raw ore is suitably ground and controlled to suitable grain sizes. These are controlled to a prescribed pulp density, after which a floatation agent is added and these are subjected to floatation. In floatation separation of copper and lead, the ore containing liquid is heated, and for example, bicarbonate is added. As a result, gaseous carbonic acid evolves, and contacts with the ore containing liquid, but the floating characteristic of lead is suppressed by the effect of the contact of the ore containing liquid with the gaseous carbonic acid. This similar effect is also obtainable even when gaseous carbonic acid is blown into the ore containing liquid. Thence, the ore containing liquid is subjected to floatation separation. In the floatation separation, it is desirable to add a capturing agent or the like in order to promote the floating characteristic of copper. In separating copper and lead, no adverse influence is given to the separation of lead and copper despite the addition of the capturing agent, and even more, this is effective for the separation.
