Tangdan copper oxide ore deposit, located in the northeast Yunnan province of China, is the largest independent copper oxide deposit in China. The ore from the deposit is characterized by low grade, high oxidation ratio and fine-grained dissemination, which results in the poor flotation recovery. The analysis of plant flotation data reveals that the loss of copper minerals into tailings is mainly with coarse size

Copper extraction Wikipedia

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.

Introduction to Mineral Processing Chevron Phillips

The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors.
