Novel reagent addition method for improved copper recovery

Abstract

The development, implementation, and optimization of novel minerals processing technologies are of paramount importance in enabling a sustainable transition to renewable energy. One such technology is the processing of coarser mineral particles by fluidized bed flotation. While much attention has been given to the design of fluidized bed flotation equipment, equal attention is warranted towards the optimization of chemistry within these new devices. The detailed analysis of flotation thermodynamics has demonstrated that the addition of a collector on bubble surfaces carries advantages for improved collector absorption and enhanced mineral surface hydrophobicity.
