sulphidation of copper oxide ores for flotation …
Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite, which can then be activated by the froth flotation plant.
Treatment of Mixed Sulfide Oxide Ores of Copper
Many ores containing oxide copper are hard to settle or filter at flotation fineness as they come from the mine and they all are much worse after contact with acid. Settling areas of 40 or 50 sq. ft. per ton-day are not uncommon; for a 5000-ton plant, a small-scale operation, this …

Copper Oxide Flotation - Mineral Processing & …
It must be noted here that the discussion in this stone pertains to oxide copper that is typically associated with economical amounts of sulfide copper (the so called “mixed sulfide-oxide” ores) and, consequently, not treated by leaching-SX (the latter is widely practiced on low-grade ores from the “oxide zone” that are not treated by flotation). In specific cases where the oxide content in the mixed sulfide-oxide ore is …

Radio Hill in Australia successfully used the Ausmelt reagent AM28 (an alkyl hydroxamate) to float mixed sulphide/oxide copper ore, increasing recovery from a low of 40 to 50% up to 70%. They used AM28 to replace sulphidisation of oxide minerals, in conjunction with standard sulphide collectors to recover sulphide minerals. Oxide minerals floated were cuprite, malachite and azurite. AM28 is a …
