Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry  in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions. By increasing potentials, on t...

The recovery and concentrate grade, used simultaneously, are the most widely accepted measures of assessing metallurgical performance. Meanwhile, new challenges are being found with more complex ores around the world, a new methodology to evaluate flotation circuits more accurately is used to keep the Mineral Industry afloat in a changing world by increasing revenues. The flotation process is d...

Numerous studies have addressed the role of ultrasonication on floatability minerals macroscopically. However, impact acoustic waves mineral hydrophobicity and its physicochemical aspects were entirely overlooked in literature. This paper mainly investigates ultrasonic power time wettability chalcopyrite, pyrite quartz. For this purpose, contact angle collectorless microflotation tests implemen...

Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation ce...

The influence of conditioning on the flotation of pyrrhotite in the presence of chlorite was investigated through flotation tests, sedimentation tests, and X-ray photoelectron spectroscopy (XPS) analysis. The flotation results show that chlorite slimes dramatically impair the flotation of pyrrhotite. Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slim...
