Minerals Special Issue Towards a Sustainable

Froth flotation was used to recover silver bearing minerals using a combination of different collectors (dithiophosphate, dialkyl dithiophosphinates, Aero 7518, Aero 7640, alkyl dithiophosphates and potassium butyl-xanthate). Mining wastes, particularly in the form of waste rocks and tailings, can have major social and environmental impacts
