Gold Ores For Clay Particles

Effect of Clay Rheology on Flotation of a

It has been recognised that the presence of clay minerals in ores adversely affect flotation performance In this study changes in rheological properties of the flotation pulps under normal operating conditions were studied with additions of bentonite and kaolinite clays at various concentrations Zeta potential measurements were also carried out to determine the changes in surface charge due

The particle size distributions quoted for gold do not reflect the particle size distribution of the ore For example 50% of the gold by weight may exist in a size fraction that only represents 10% of the ore by weight Also the variation in the weight distribution of gold with particle size depends upon the nature of the ore and for alluvial
