downstream process is sensitive to grind, otherwise the costs associated with achieving the product size would outweigh the downstream benefits. Therefore an SAB or SABC circuit is preferred because of the more stable product generated in this type of circuit. Furthermore, large circulating loads are often encountered if trying to produce a grind size less than 75 µm. This …

To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2. Calculating from the atomic …

 · The grinding circuit started up close to the design to provide minus 500 micron slurry. The 50% solids (wt) ground ore slurry proved to be difficult to transport to and process at the Key Lake Mill. Slurry containing high concentrations of high density pitchblende (about spgr ) and low concentration of stabilizing clays, would settle in containers. Ore transport …

Mineral processing is no exception, with cyclones often being an integral part of closed-circuit grinding systems. The centrifugal force applied to particles being spun within a cyclone is many times greater than gravity, allowing the device to achieve a much better separation efficiency based on either (or both) particle size and density. Larger or more dense particles are directed …

that most grinding circuits closed by hydro cyclones operate with high circulating loads that range between 230 – 450%. (See figures 3, 4, 5 and 6 for circuit types). The grinding operation in a mineral processing facility typically consumes the majority of the energy used. In addition to energy these mills consume special steel

The cyclone feed contains 35 % solids by weight, • A mineral processing plant is a large consumer of water. In a plant treating 10,000 t/d of ore, typically 20m 3 /min of water is required, which is expensive if some form of conservation is not practised. • For optimum performance, therefore, there is a water requirement which produces optimum slurry composition in all parts …
