(2) Rolling and isostatic pressing are used, with a large specific gravity, which can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the effective volume of the ball mill, thereby increasing the amount of grinding material added.
Based on the iron ore processing experience and necessary processing tests, Prominer can supply complete processing plant combined with various processing technologies, such as gravity separation, magnetic separation, flotation, etc., to improve the grade of TFe of the concentrate and get the best yield. Magnetic separation is commonly used for magnetite. Gravity separation is commonly used for hematite. Flotation is mainly used to process limonite and other kinds of iron ores.

Based on the overall structure of porphyry copper-molybdenum deposits, there are usually three types of minerals in symbiosis, namely copper, molybdenum, and sulfur. It should be pointed out that because of the relatively low grade of molybdenum ore, its output is a mixture of copper and molybdenum. It is presented in the form of concentrate, which is then systematically separated from copper and molybdenum to obtain molybdenum concentrate and copper concentrate. In the flotation of copper-molybdenum ore, two more aspects of beneficiation operations were implemented. After the operation is completed, molybdenum concentrate can be obtained.
Spiral classifier is widely used to control material size from ball mill in the beneficiation process, separate mineral sand and fine mud in the gravity concentration, and clean mud and water in washing mineral process.
Stockpile ore delivered by FMR’s customers initially passes through a three-stage crushing circuit consisting of a primary jaw crusher followed by secondary and tertiary cone crushers. The feed from the secondary and tertiary crushers is graded by a double deck screen that removes undersize material from the circuit. The crushing system produces a P80 product size between 6 and 8mm which is then transferred and stored in a 1000 tonne mill feed bin.
Corundum in nanoparticulate form is highly interesting for the chemical industry. "There are reports that catalysts with a carrier material made of corundum work more efficiently for the production of ammonia," says Ferdi Schüth, Director at the Max-Planck-Institut für Kohlenforschung. "In other catalytic processes, such as the production of synthetic fuels, the higher stability could be essential." Nanoparticle form of corundum may therefore find numerous applications in the future because now it is easily accessible through the simple mechanochemical process found by the Mülheim chemists.
Magnetic separation is a process of separating the components of mixtures by the usage of the magnets for attracting magnetic materials. A process which is used for the magnetic separation, detaches the non-magnetic material from those that are magnetic. Such technique is not useful for all, but only for the few minerals like the paramagnetic and ferromagnetic. Not all the metals are magnetic, silver, gold and aluminum are some of the examples.
