Copper Flotation Plant in Pakistan | CNFREE

The copper flotation plant in Pakistan has a processing capacity of 1500tpd. The raw ore was characterized by simple composition. It consisted of metallic minerals (copper pyrite and pyrite) and non-metallic minerals (quartz and chlorite). The multi-element analysis results showed that Cu was the valuable element. The Cu grade of the raw ore was 0.80%.

60 Centuries of Copper: The Flotation Process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
