During the operation of sub-aeration-type flotation machines, Morash noted that certain ores over-flocculated and required excessive quantities of frothing reagent to maintain the standard recovery level. Crowders were introduced to accelerate froth discharge velocity, which increased the transportation capacity of fragile froths.

The flotation sub-processes in an RS differ from the processes that take place in other types of flotation machines (impeller- and column-type machines). In an RS, flotation proceeds in two successive stages: first the particles attach to the bubbles in the reactor; then the mineralized bubbles are removed from the pulp in the separator. In all ...

No accurate comparison is possible between the power consumption of the three types of flotation machines, because it depends so much on the character of the ore treated. In the absence of definite test data, it is best to assume, if an approximate figure is needed, that the single- stage flotation of a simple ore will require 1.0 kilowatt-hour ...

The flotation dynamics can be improved by increasing the gas holdup to a certain value because the number of bubbles per unit volume increases; however, excessive air holdup will have negative impacts on the flotation effect because this will significantly reduce the resident time of the pulp in the tank body of the flotation machine. Thus ...

Frothers are usually added to the pulp just before its entrance into the flotation machine. The quantity of frother varies with the nature of the ore and the purity of the water. In general from .05 to .20 lbs. per ton of ore are required. Some frothers are more effective if added in small amounts at various points in the flotation machine circuit.
