60 Centuries of Copper The Flotation Process

This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can

Molybdenite flotation from copper/molybdenum

Single-stage rougher flotation after ozone conditioning can provide a molybdenum concentrate at a recovery of more than 90% and a rougher concentrate grade higher than 20% Mo in some cases. Subsequent cleaner flotation with additional ozone conditioning results in relatively copper-free molybdenum concentrates containing as much as 52% Mo.

Molybdenite flotation from copper/molybdenum concentrates

Molybdenite flotation from copper/molybdenum concentrates by ozone conditioning. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite varies between 40% and 90% at a concentrate grade of 5% to 10% Mo.

Investigation of Flotation Parameters for Copper

According to these results, it was observed that enargite in the mixed ore can first be recovered at pH 4 followed by chalcopyrite recovery at pH 8. As content in both chalcopy- rite concentrate and final tailings was reduced to below 0.5mass%. The enargite concentrate can be treated separately for As removal.
