| The mineral characteristics of the three locals were similar and mainly composed of copper, lead, zinc, and iron sulfides. In order to facilitate treatment, the ores from the three locals were equally admined and flotation tests were performed. The best separation was achieved when copper and lead sulfides ware floated prior to zinc and iron sulfides. Iron sulfides were recovered in the scavenging. Flotation collectors used in the copper and lead circuit were Minerec B and Potassium ethyl xanthate, and amyl xanthate for zinc and iron sulfides. At a reasonable point of concentration the chemical analysis of the concentrates showed 23.3% Cu of copper concentrate, 68.7% Pb of lead concentrate, and, 47.8% Zn of zinc concentrates, with recoveries of about 70 to 80% in the copper, and, zinc concentrates. |
