oxide copper ore flotation

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.
