OSTI ID:6910212
This patent describes a process of froth flotation for the recovery of a sulfide mineral, or a sulfidized oxide mineral, from an ore containing the sulfide mineral or sulfidized oxide mineral. It comprises: subjecting the ore in the form of an aqueous pulp to froth flotation in the presence of a sufficient amount of methylene bisxanthate to act as a collector reagent for the sulfide mineral or sulfidized oxide mineral.
