Abstract:
The present invention is directed to a method for selectively recovering a sulphide mineral from an ore applying a collector being an alkylated triphenyl phosphorothionate. Further, the present invention is directed to the use of said alkylated triphenyl phosphorothionates to separate a target mineral from iron sulphide and/or silicate gangue.
