The comminution of ores consumes a high portion of energy. Therefore, different pretreatment methods of ores prior to their comminution are considered to reduce this energy. However, the results of pretreatment methods and their technological development are scattered in literature. Hence, this paper aims at collating the different ore pretreatment methods with …

There are diverse types of comminution machines used for breaking down materials. Here are some common machines used in comminution process: Roll Crushers: A type of compression crusher often used in mining and aggregate industries. They consist of two large rolls, usually made of steel, with each roll rotating towards the other.
total energy is estimated to be consumed in mining equipment, this category covers a very wide variety of different equipment, as indicated in the figure. Comminution, consuming close to 40% of total energy contains a single piece of equipment—the grinding mill—that is typically the largest single consumer in a mining operation.
Ore that is less than 40 mm but greater than 8 mm is conveyed to the lump stockpile. Ore that is finer than 8 mm, but greater than 1 mm is conveyed to the fines stockpile. Any ore that is finer than 1 mm in size is conveyed to a de-sanding plant consisting of cyclones, upper current classifiers and two stages of spirals for further beneficiation.
