    Effect of pH on Copper Flotation Recovery VS Mass Pull

    Oct 01, 2015 Here, rougher flotation is most Selective at a pH of 9.5 as pH levels in the 9 to 10 range yielded 1 to 2 better recoveries. Mineralogy data also supports this and shows between 3 and 10 of the copper is present as low-grade middlings in pyrite, and further supports the benefit of floating middlings pyrite to maximize copper rougher recovery.

    The Effects of Water Recycling on Flotation at a North

    Microbial cells can cause significant changes in the surrounding water chemistry, particularly with respect to pH and ORP and can metabolize certain flotation additives, all of which could have serious effects on mineral flotation. The effects of microbial cells on flotation will be investigated in a subsequent paper. 4.2. Flotation Testing

    The Importance of pH in Flotation

    Aug 10, 2015 The Importance of pH in Flotation. In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important.

    Development of a Combined Flotation and High Pressure

    The present study focused on the re-processing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.
