Application of image processing in mineral industry: a ...

In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution. As a rule, comminution begins by crushing the ore to below a certain size and finishes by it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral

Gold extraction

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include , concentration, , and pressure oxidation prior to

The effect of phyllosilicate minerals on mineral

· Often broadly classified as ‘clays’, phyllosilicate group minerals exist as common gangue components in many low grade ores e.g. serpentine in Mt. Keith nickel sulphide ore, Western Australia Senior and Thomas, 2005 and talc in the Bushvelt Complex, South Africa Schouwstra et al., 2000. In the past, the processing of some of these ores has been problematic with difficulties such as reduced

Mineral processing

Dewatering is an important process in . 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 handling and concentrates to be transported easily, allow further to occur and to dispose of the gangue
