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 ...

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

ABSTRACT. The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

Modified thionocarbamates are used in copper-gold ores, which allow some selectively against iron sulfides even at a pH value less than 10. Many gold plants use a blended collector or separate collectors as needed based on mineralogy and ore chemistry. Copper sulfate is commonly used as an activator of gold-bearing iron sulfides in flotation ...
