ABSTRACT:
An invention including an apparatus and process for generating small bubble foam using foam generating equipment in manufacturing processes such as benefication, flotation, flocculation, and for dust control in size reduction processes of a substrate, whereby a continuous, precise amount of a defactant is added to the treated substrate after introduction of the foam and processing of the substrate, in order to neutralize the residual small bubble foam so that the residual foam does not interfere in subsequent processes.
