Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
SUMMARY OF THE INVENTION In my new process for producing copper and sulfur from sulfidic copper ore, the copper ore is first ground advantageously autogenously with grinding boulders obtained from converter slag, to reduce the ore to finely divided particles of cupriferous materials and gangue materials. The finely divided copper ore is then ...

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by …
Applied across the industry, improved coarse particle flotation can result in an additional 0.5 million to 1.5 million metric tons of annual copper production by 2032. If applied across all metals found in sulfide deposits, the technology represents potential value creation of $9 billion to $26 billion per year.
