quartz in the cationic flotation [11]. In summary, the PZC of quartz occurs at pH 2. Therefore, quartz is negatively charged above this pH. Collector adsorption is due to the electrostatic interaction on quartz. In the case of cationic flotation, the depression of quartz
Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable. From past ...
· Quartz is, in most cases, the major gangue mineral found in the manganese ore. Mn iron, dissolved from the surface of ore, will determine the interfacial properties of the particles and, thus, their flotation behavior.
