a new application for flotation of oxidized copper ore

a new application for flotation of oxidized copper ore

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant

evaluation of sodium isobutyl xanthate as a collector in

evaluation of sodium isobutyl xanthate as a collector in

Flotation occurs most efficiently in the range 38–106 lm this is emphasised by the reduced percentage passing these size fractions in the particle size distribution of the tailings indicating efficient milling and flotation. Conclusions The Palabora copper ore ground 45 % passing 75 lm was successfully froth-floated with SIBX collector at varying dosages

The prominent parameters investigated in this network were pH, collector, frother and …

flotation of oxide copper ore with sodium oleate from the

flotation of oxide copper ore with sodium oleate from the

Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded 14.4% Cu with 83.3% recovery in a rougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silicate, quebracho, and pine oil were examined. At the optimum dosages, the grade increased to 20.1% Cu with 76.4% recovery
