a) providing a slurry comprising the at least one material dispersed in a liquid,

b) contacting the slurry with a collector composition,

c) subjecting the at least one material to beneficiation to result in a beneficiated material, and

c) recovering the beneficiated material,

wherein the collector composition comprises a mixture of collector A and collector B;

wherein the collector A are by-products obtained by hydroformylation of octene isomers and the collector B is selected from the group consisting of diesel, kerosene and C₈-C₂₀olefins;

wherein the by-products obtained by hydroformylation of octene isomers comprise
