Flotation Circuit - an overview ScienceDirect Topics

Flotation circuits are simple for Indian coals. Concentrates can be produced in one stage of flotation, and recleaning of the products may not be generally necessary. In the case of highly oxidised coal, two-stage flotation may be required to be incorporated, with rougher cells and cleaner cells.

Molybdenum Ore Processing by Flotation

05-05-2016  On many molybdenum ores a high-grade concentrate can be made in this four-cell coarse flotation circuit. The “Sub-A” Flotation Machine is the only unit that can successfully treat such coarse feed without sanding up. Tailings from this coarse flotation circuit go to a separate regrind circuit. Regrind Circuit. This consists of a Steel Head Ball Mill in closed circuit with a “Sub-A” Unit Flotation Cell and

17-10-2016  Flotation Circuits for Air-Lift and Pneumatic Cells. An air-lift machine can often be run as a rougher-cleaner cell, as in circuit No. 5 (Fig. 52), by taking a finished concentrate off the first few feet and returning the froth from the rest of the machine to the feed end. This method is also applicable to pneumatic cells, but its use is not common.

12-08-2015  The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit. The mineral has been separated from the ore, there for it is in a concentrated form from
