  • Froth flotation Wikipedia

    Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.Reagent Research Group , Centre for Minerals Research,The current research focus of the facility is the role of depressants in flotation and the synergistic reactions between reagents in flotation systems. Most work is focused on the flotation of platinum

    Abstract—This study investigated the effect of pH on the recovery and grade of the Platinum Group Metals (PGMs) and base metal sulphides from the UG2 ore of the bushveld complex. This was achieved through running a series of test work in a Denver flotation cell at varying pH 6-11 at constant reagent dosage. The UG-2 reef is characterized by two predominant gangue phases i.e. chromite and Flotation Platinum Reagents mahamayaresidency,floatation system and equipments for gold and platinum. floatation system and equipments for gold and platinum.

  • Introduction to Mineral Processing Chevron Phillips

    Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.Copper-Molybdenum ores Danafloat Home,Flotation is conducted at high pH levels often times greater than 11 using lime to ensure good depression of sulphide minerals, particularly iron sulphides and copper. Other depressants used include cyanide and Nokes reagent (thiophosphorous or thioarsenic compounds).
