Size reduction is the initial stage of Processing. Most of the times, Minerals can not be used as such after mining. Among the mineral Ore, we have different types of material of different characteristics. We have to eliminate our target particles from the cosolidated sample. Once we get the sample in particulated form, its easy to classify different particles in groups by Size analysis, gravity separatins, jigging, Cyclones, watering-dewatering etc
Reduction of particle size is used in order to separate the valuable from a mixture of valuable & gangue for that process ,optimization of ore processing operations and the Increase of the specific area because most of the reactions involves solid particles, the rate of reaction is directly proportional to contact area .
To improve handling characteristics
Increase the surface area because most of the reactions involves solid particles, the rate of reaction is directly proportional to contact area with a second phase.
Reduction of particle size in order to separate the valuable from a mixture of valuable & gangue for that process.
Achieve intimate mixture to optimize the process.
To mix solid particle more intimately.
size reduction increases the reactivity of the materials with substances. Size reductions increases reactivity, thus reduces the reaction time.
