Self-induced mechanical air flotation eliminates need for auxiliary air compressors or blowers. Processing is often improved with the aid of a chemical injected into the water upstream from the float cell. These compounds break oil-in-water emulsions, gather suspended solids, and stabilize the air bubbles to promote froth flotation.

2016-3-23 · Froth launders have a very generous slope as they wrap around the vessel. The outlet piping is obviously located at the low point of the launder. The bitumen froth then gravity flows to a deaeration column where air is removed from the froth to facilitate pumping to downstream equipment. Froth launders are typically insulated to prevent heat loss.

Effects of Collectors and Frothers on Copper and ...

2019-5-14 · In the plant there are other factors that need to be considered. If large flotation cells are used, for example, 300 m 3, then the operator has to ensure that enough frother is added to have a stable froth. Also, froth crowders may be considered to reduce the residence time of the particles in the froth phase before entering the launders.

Froth flotation is the standard method of concentration used in the copper industry. About 75 percent of all copper is produced by this method. The most significant technological development in flotation in recent years is the column flotation cell, which is being installed at most concentrators (Berkeley Study 1985).

Cell Design

2016-3-22 · Launders are designed with a slope of about 10}153 for smooth transportation of froth without blockage in the launders. The design of launders varies with cell size and type. The launders are located on opposite sides adjacent to the feed and discharge boxes in rectangular cell tank designs, as shown in Figure 1.
