(PDF) Application of Knelson Concentrator for Beneficiation of Copper
At NCK, the beneficiation of copper and cobalt ore involves a combination of concentration by froth flotation and classical gravity separation by spirals and shaking tables. A crushing–grinding–flotation system is used to produce a 7–8% cobalt and 25–30% copper bulk concentrate. The flotation reagents regime is based on a strengthened ...
These Copper Oxide Ore Beneficiation Methods Greatly …
Copper exists in nature mainly in the form of sulfide ores and oxide ores, of which sulfide ores are the most important, while the slow oxidation and metamorphism of sulfide ores generate oxide ores. Among them, oxidized copper ore refers to copper ore with an oxidation rate greater than 30%.It is generally located in the oxidation zone above the ore bed, which has …
