Specific Dosage Selection of Collecting Reagents

The function of collecting reagents is to efficiently collect useful minerals and improve the flotation recovery rate. More specifically, they modify the hydrophobicity of the mineral surface, enabling the minerals to be floated to adhere to the surface of air bubbles and float up—thereby achieving the goal of mineral separation. To ensure these reagents exert a more efficient effect, the following is an explanation of the specific dosage selection of collecting reagents:

The interactions of collecting reagents on the mineral surface include physical adsorption, chemical adsorption, and surface chemical reactions. The adsorption of collecting reagents is closely related to the flotation behavior of minerals. Within a certain concentration range of collecting reagents, as the reagent concentration increases, the adsorption amount rises, and the flotation recovery rate increases significantly. After the concentration reaches a certain level, the extent to which the recovery rate increases alongside the rise in concentration and adsorption amount diminishes. When the concentration of collecting reagents is excessively high, the adsorption amount may still continue to increase, but the flotation recovery rate no longer rises and may even decrease instead.
