Abstract
The possibility of activation of lead-zinc ore by products of non-stoichiometric interaction of potassium butyl xanthate with heavy metal salts is investigated. It is possible to regulate the collecting properties of the mixtures obtained by changing the ratio of components. To assess their activation efficiency, the criterion of “surface flow power” of the film of collector derivatives at the gas-liquid interface was used. A mechanism is proposed to reveal the causes of changes in flotation indices when using xanthate precipitates of various metals.
