Abstract
A process for beneficiating a feldspar and/or feldspathoid containing feed material which comprises magnetic impurities, non-magnetic impurities and non-magnetic minerals to be beneficiated, the process comprising the steps of providing said feed material, forming an aqueous composition comprising said feed material and a magnetic enhancer reagent and subjecting said aqueous composition to wet magnetic separation.
Claims25
A process for beneficiating a feldspar and/or feldspathoid containing feed material which comprises magnetic impurities, non-magnetic impurities and non-magnetic minerals to be beneficiated;
- said process comprising:
- (a) providing, obtaining or preparing a feldspar and/or feldspathoid containing feed material which comprises magnetic impurities, non-magnetic impurities and non-magnetic minerals to be beneficiated;
- (b) forming an aqueous composition comprising the feldspar and/or feldspathoid containing feed material and a magnetic enhancer reagent, wherein the magnetic enhancer reagent comprises one or more magnetic oxide particulate and one or more surface active agent;
- (c) subjecting said aqueous composition to wet magnetic separation to produce a non-magnetic separation product having a reduced level of magnetic and non-magnetic impurities, and a magnetic separation product comprising the magnetic and non-magnetic impurities removed from the aqueous composition.
