Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill
Probably the most significant area of change in mechanical flotation machine design has been the dramatic increase in machine size. This is typified by the data of Fig. 8, which shows the increase in machine (cell) volume size that has occurred with a commonly used cell manufactured by Wemco.The idea behind this approach is that as machine size increases, both plant capital and operating costs

Since 2004, the company has been carrying out a fundamental review of the mechanics of flotation developing proprietary CFD models
2016-12-19 control of a flotation process are classified as follows: The tendency of the ore to have variable physical, metallurgical, and surface properties produces significant changes in a flotation circuit. The particle size range of the flotation feed can be substantial because of ore hardness changes and changes in the operation of the grinding circuit.

These resources comprised 12 metallurgical domains with widely varying metallurgical characteristics. This resulted in a very complex process plant design. The final design had a capital cost of approximately $200M.
