ZongXian Zhang, in Rock Fracture and Blasting, 2016. Thermally Assisted Liberation in Comminution. Heating and quenching rock can enhance liberation and increase mineral recovery in mineral processing. If the objective of size reduction is to liberate the valuable mineral component of an ore, then ideally fracture should follow intergranular paths, that is, grain boundaries.

· The increase in mineral recovery can similarly be attributed to both the increase in air rate and the increase in air recovery, yielding a faster flowing, more stable froth, hence a higher recovery of both attached valuable particles and nonselectively entrained valuable particles. The bubbles are therefore less coated with valuable hydrophobic particles, however a more mobile froth ensures a

recovery. Similarly, if the purest mineral grain that contains the metal of interest is removed, this will be the maximum grade that can be produced by a physical separation, and so the 0% recovery end of the curve terminates at an assay less than or equal to the assay of the purest grains available in the ore. In the graphs shown in Figure 2

Mining Recovery is usually a percentage estimate of insitu ore recovered after mining has taken place. It is frequently described as mining loss which is economic mineralisation that has been lost during the mining activity. Mining Dilution is the percentage of material added to the insitu ore during mining.

utilization ratio of mineral resources; furthermore, they directly influence the economic benefit of the mining enterprises. Therefore, the calculation and management of mining loss rate and dilution rate have been being treated as the central work of mining industry over a long time and also is the technical subject for a lot of supervisory engineering staffs to study and solve constantly [1

The metal recovery rate, or also known as the mineral recovery percentage, indicates what percentage of valuable metals are expected to be available for sale after the refining process has taken metal recovery rate can be found in a mining company''s National Instrument 43101 or in a similar applicable international reporting standard.

The flotation columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m 3. This is done as they are cheaper per unit volume than smaller cells, but they are not able to be controlled as easily as smaller cells. This process was invented in the 19th century in
