Flotation of Calcium Minerals with Combination of Reagents of Different Molecular Structure

Resumo

The influence of non-ionic compounds in combination with sodium oleate on the contrast behavior of flotation response of calcium minerals is investigated theoretically and experimentally. The flotation and adsorption analyses are carried out with monomineral fractions of calcite and scheelite, while the flotation process analysis is conducted with an ore material screened into size grades of -44 and -15 urn. The process conditions of the highest difference in adsorption of oleate and contrast in extraction of scheelite and calcite are found. The conditions of the maximum depression of calcite in the rougher flotation circuit are determined.
