Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cusulphide ore. The samples were ground as dry and wet with both ...

Despite the effective depression of pyrite by the combined use of sodium metabisulfite (MBS, Na 2 S 2 O 5) and HiCr steel grinding media in high salinity water, many copper processing plants still desalinate saline water with a considerably high cost, which motivated this study to identify the best chemical solution to maximise the depression ...
Autogenous and semiautogenous mills are commonly used in the primary grinding stage in ore processing plants, which excludes medium and fine crushing. The alternative is highpressure grinding rolls, which can reduce electricity consumption compared with autogenous and semiautogenous grinding.
Heap leaching is a method for extracting copper from ore by piling it into an outdoor pile, then sprinkling acid over the heap. The acid reacts with the copper sulfide in the ore and slowly dissolves it away as a solution of sulfuric acid and copper sulfate.
Copper ore with a particle size between 01 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was performed.

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 Copper ore crushing process 1.

The first notable application for copper ore came in 1995 at the Cyprus Sierrita copper mine in the USA. However, on account of the extremely abrasive ore, no economical service lifetimes could be achieved for the grinding rolls. The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru.

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

1. Crushing process The copper ore that needs to be processed must first go through the crushing process. The vibrating feeder is fed through the silo, and the vibrating feeder is evenly sent to the jaw crusher for primary crushing, and the large raw ore is broken into small pieces of ore.
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.
