Newly refined paraffin hydrocarbons, if pure, will not froth to a sufficient extent to make them efficient flotation agents in the agitation-froth or pneumatic processes. Certain other substances, although possessing the property of froth formation in these processes, exclude practically all solid matter from the froth.

When agitation is not of prime importance, air-lift and pneumatic machines are usually as effective as the others and require less power in operation. They have the disadvantage, however, that the pulp must be conditioned ahead of flotation ; no high-speed conditioning effect, such as is possible with an impeller or rotor, can be obtained …

The Kraut Machine is not used as widely as the two just mentioned. Its particular advantage is the intensity of the agitation produced between the rotor and the stationary cylinder, which is probably greater than that obtainable in any other flotation machine. On this account it is especially suitable for the flotation of gold ores.
