Abstract:
Water is one of the important parameters in flotation, and represents 80–85% of the volume of mineral pulp processed in flotation circuits. Our recent studies revealed that the ground sulphide minerals in contact with water generated H2O2, but its effect on the oxidation of pulp components, and hence in deteriorating the concentrate grade and recovery in flotation, has not been explored yet. In this study, effect of two types of water on formation of H2O2, an oxidizing agent stronger than oxygen, was investigated. It was shown that process water generated more H2O2 than tab water. This trend highlights the importance of understanding the mechanism of between process water and sulfide minerals on flotation.
