After sieving the sample is bagged according to grain size, usually resulting in three classifications; >.5mm, .25mm-.5mm, and <.25mm. Each bag is labeled with the sample name and grain size. Usually only the .25-.5mm sample is …
Crushing and grinding is the most costly step in mineral processing because the power needed to liberate the minerals is very high. In this sense, grinding is commonly said to be the key to good mineral treatment and the major consumer of energy, accounting for up to 50% of a concentrator's energy consumption ( Table 6.3 ).
Sieving is a separation technique based on the difference in particle size. The sieve is responsible for retaining the larger particles. On top of size, other factors play a role in determining whether a particle will pass through the sieve or not; format of the particle whether the particle will fall where there is an opening or on the mesh of ...

In the mineral processing process, it is often necessary to understand the particle size composition of the material. In order to accurately identify the particle size composition of minerals, sieving analysis must be carried out to know how much each coarse and fine particle occupies in the mineral material.
