FLOTATION REAGENTS AND FLOTATION PROCESSES UTILIZING SAME

摘要

Methods of enhancing recovery of value sulfide or precious minerals from an ore containing Mg-silicate, slime forming minerals, and/or clay by subjecting the ore to a flotation process performed under acidic conditions, in conjunction with the addition of a froth phase modifier agent to the ore, are provided herein.

主权项

1. A method of enhancing recovery of a value sulfide mineral and/or a precious metal-bearing mineral from an ore containing said mineral and/or precious metal-bearing mineral, and one or more of a Mg-silicate, a slime forming mineral, and/or a clay, said method comprising:
adding to one or more stage of a froth flotation process performed under acidic conditions a froth phase modifier comprising a polymer having one or more functional group selected from the group consisting of sulfonate groups or acids thereof, phosphate groups or acids thereof, phosphonate groups or acids thereof, phosphinate groups or acids thereof, hydroxamate groups or acids thereof, silane groups, and silanol groups,thereby enhancing recovery of a value sulfide mineral and/or a precious metal-bearing mineral from said ore.
