Modeling flotation separation in a semi-batch process
Flotation separation is a process used in many industries to separate one constituent from another. Dispersed air flotation is commonly found in mineral processing (mineral flotation) and paper recycling (flotation deinking). In these processes, bubbles are formed by mechanical agitation or sparger air injection and chemicals (i.e., frothers ...

Ethiopia 200 TPH Alluvial Gold Processing Plant
This setup is an alluvial gold process plant. The loader feeds the raw material into the hopper, and the stone enters the plate feeder from the lower part of the hopper; the material is into the Derocker, and then fed to the rotary scrubber evenly, the larger than 50mm scrap will be separated by Derocker and transferred to the ground as a waste pile.

Flotation as a Separation Process
The importance of the flotation process to the economy of the whole industrial world is considered enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up (1).
