    Oxide copper ore flotation with 800 gton 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.
