Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

In contrast to the sulphide ores, these oxide ores cannot be beneficiated by flotation or other conventional mineral processing techniques. One potential concentrating method would be the solid state pyrometallurgical reduction of the ore followed by upgrading using magnetic separation.

The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about 8. According to Bond [4], the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as

We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher. Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be ...

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate

Many variables influence the size reduction performance in a mill, including the media size, shape & quality, the properties of the incoming ore feed, the ratio of feed to media and the speed of the mill. Since grinding media performance is critical to mineral processing operations, it's important to partner with a quality supplier such as SGI.
