Abstract: Methods of enhancing recovery of value sulfide and/or precious-metal minerals from an ore containing said minerals and a Mg-silicate, slime forming mineral, and/or clay, and which is subjected to a froth flotation process, by adding to one or more stage of the froth flotation process a froth phase modifier having a polymer containing one or more functional groups, and optionally a monovalent ion modifier enhancing agent, thereby enhancing recovery of a value sulfide mineral and/or a precious metal-bearing mineral.

Abstract: Methods of enhancing recovery of value sulfide and/or precious metal-bearing minerals from an ore containing such minerals as well as Mg-silicate, slime forming minerals, and/or clay by adding a froth phase modifier agent to the ore, and subjecting the ore to a froth flotation process performed under acidic conditions, are provided herein.
