Keywords flotation process optimization Taguchi orthogonal array ANOVA 1 Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited Kabuda et al 2011

Simply said a Flotation Collectors is a chemical used to make the surface of minerals which is metallic hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say This chemical used will behaved in a way as a wax would when you applied it to your car After wax or hydrophobic agent is adhered to the surface that surface with see water pearlaway

Copper is floated in the first differential flotation stage at a 1011 pH with lime Xanthate dithiophosphate and thionocarbamate collectors are used as explained much more extensively in the copper flotation section The copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained
