Oxide Lead Treatment Extraction by Flotation Gravity ...

27.04.2016  Oxidized ores give trouble from the time the ore enters the mill ore bin until the tailings reach the tailings pond. The ore is removed from the primary bin by means of an oversize apron feeder of the heavy duty type. Louvers should be available on the front or sides of the ore bin to enable the operator to poke the ore down into the apron feeder and thus prevent

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. To upgrade the rougher concentrate,
