Abstract
Froth flotation processes, useful for beneficiating base metal mineral values from metal sulfide ore, utilize a collector comprising an N-butoxycarbonyl-O-alkylthionocarbamate selected from the group consisting of N-butoxycarbonyl-O-methylthionocarbamate, N-butoxycarbonyl-O-ethylthionocarbamate, N-butoxycarbonyl-O-propylthiononocarbamate, N-butoxycarbonyl-O-butylthionocarbamate, N-butoxycarbonyl-O-pentylthionocarbamate, and N-butoxycarbonyl-O-hexylthionocarbamate.
Claims11
A froth flotation process for beneficiating an ore, comprising:
- forming a slurry comprising water and particles of an ore, the ore containing sulfide minerals;
- intermixing said slurry with effective amounts of a frothing agent and a collector to form a froth containing beneficiated sulfide minerals;
- and
- collecting said beneficiated sulfide minerals;
- the collector comprising an N-butoxycarbonyl-O-alkylthionocarbamate selected from the group consisting of N-butoxycarbonyl-O-methylthionocarbamate, N-butoxycarbonyl-O-ethylthionocarbamate, N-butoxycarbonyl-O-propylthionono-carbamate, N-butoxycarbonyl-O-butylthionocarbamate, N-butoxycarbonyl-O-pentylthionocarbamate, and N-butoxycarbonyl-O-hexylthionocarbamate.
