gold froth flotation

  • Sulphide Flotation an overview ScienceDirect Topics

    Iron hydroxide coatings hamper gold flotation but are hardly the main cause for free gold rejection. At Batu Hijau, manganese hydroxides were strongly enriched on the rejected free gold particles. In most flotation plants, sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation.
