The selectivity of copper flotation is illustrated in Fig. 6. The highest selectivity in copper flotation was attained with thiosulfate in the beginning of flotation when the flotability of pyrrhotite was not so strong. Download : Download full-size image; Fig. 5. Effect of calcium and thiosulfate ions on copper flotation (KeX 75 g/t).

Selectivity and power of frothers in copper ore flotation 517 The ore was crushed in a jaw crusher to obtain particles smaller than 1 mm in size. Prior to each flotation experiment, the crushed material was wet ground in a steel ball mill. The size distribution of the ore, used as the flotation feed, is presented in Table 1. Table 1.

The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.get price

Commercial porphyry copper ores usually contain copper grades between 0.5% and 2%1. Minor amounts of gold are often present in these orebodies2.
