flotation. A comminution model representative of the CVO, combined with the flotation data collected during the surveys, was used to investigate the potential benefits of reducing the variability in classification efficiency. The results were presented in terms of final recovery, size specific energy, and revenue.
In froth flotation, the probability of flotation and hence the rate of flotation is directly determined by three microprocesses: collision, adhesion and detachment (Trahar and Warren, 1976). To obtain an improved understanding of the complete flotation process, it is necessary to analyze these three microprocesses quantitatively.

The present paper deals with the development of process flowsheet for recovery of high-grade graphite from rougher graphite concentrate for use in industrial applications. In the present investigation, since the coarser graphite flakes have a higher demand, an attempt is made at every stage of comminution, and flash flotation experiments have been carried out, and the …

4. Comminution System To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.

Comminution and flotation circuits are frequently perturbed by disturbances, such as feed particle size variations, ore hardness and varying mineral liberation, which can have a significant impact on the recoveries and grades. Although advanced control strategies can neutralize many of these
Comminution is usually studied with the aim of achieving a target grind size whilst maximising tonnage rate and minimising energy use. Conversely, flotation is often studied through a lens of maximising grades and recovery of the valuable elements in the flotation feed.
Hence, a flotation circuit model of the plant needed to be developed to reflect the upstream comminution changes on the flotation recoveries. This is because p80 and throughput of the comminution circuit is related, i.e., throughput can be increased by increasing p80 of the comminution circuit. However, there is a threshold p80 for flotation ...

In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve this, comminution …
