REACTOR DE FLOTACAO E PROCESSO PARA A FLOTACAO

摘要

A flotation method in which the gas bubbles for inducing flotation of the solids in the liquid are produced by a chemical reaction, for example a decomposition of hydrogen peroxide to oxygen and water, induced by catalytic action. The catalyst is on the walls of the flotation reaction and the substance to be flotated is introduced tangentially and caused to flow downwardly and thus upwardly in the reactor.
