| Abstract Scope |
Worldwide, galena PbS is the most abundant mineral sulfide for obtaining metallic lead, however, mineral deposits are frequently associated with impurities that contaminate the concentrate obtained during flotation, such as pyrite or arsenopyrite, these minerals can be depressed efficiently with the addition of ordinary Portland cement (OCP), however its effect on collectorless flotation galena is unknown. In this work, the depressant action of OPC on galena flotation as a function of pH was analyzed. Under highly alkaline conditions pH 12, a % w/w cumulative flotation of galena of 71.5 is obtained with a pulp potential of -44.2 mV, with an electrical conductivity (k) of 1246 micro-Siemens/cm, the decrease in the alkaline pH of the pulp by adding sulfuric acid depresses the flotation of galena, thus, at pH 9 a separation of around 10.81% w/w was obtained, with an oxidizing potential of +352.2 mV. |
