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 ...

JXSC supports customized copper processing plant and equipment, fully suitable for separating copper oxide ore (azurite, cuprite and malachite); copper sulfide ore (chalcopyrite, bornite and chalcocite) and natural copper.
The operating practices in the beneficiation of porphyry copper ores from Chile are reviewed. The factors which affect plant metallurgical results are discussed including: ore mineralogy, reagent scheme and flowsheet. Over the past decade, a decline in plant metallurgy at a number of plants occurred mainly due to the changes in ore …
But heavy medium beneficiation or heavy liquid beneficiation is an effective method for spodumene beneficiation. For example, the mineral processing staff of the United States Bureau of Mines also used tetrabromoethane as the heavy liquid (density 2.9529 g/cm3) to carry out a continuous test of the heavy liquid cyclone separation of …

Copper slag is a metallurgical waste that is disposed by way of stockpiling at designated dump sites within a mining site. The observed depletion of high-grade iron ores in Botswana and the environmental hazards associated with disposal of untreated metallurgical waste, presents an opportunity for research on secondary sources of iron …
Globally a large volume of copper slag (Table 1) is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [9].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [6].Table 1 illustrates the magnitude of slag …

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. The actual experimental test ...
