Abstract
Froth flotation processes, useful for beneficiating base metal m ineral 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-etkylthionocarbamate, N-butoxycarbonyl-O-propylthiononocarbamate, N-butoxycarbonyl-O-buylthionocarbamate, N-butoxycarbonyl-O-pentylthionocarbamate, and N-butoxycarbonyl-O-hexylthionocarbamate.
Claims (11)
1. 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.
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.
2. The process of Claim 1 in which said collector is intermixed with said slurry in an amount in the range of about 0.005 to about 5 lbs per ton of ore in said slurry.
3. The process of Claim 1 in which said collector is intermixed with said slurry in an amount in the range of about 0.1 to about 2 lbs per ton of ore in said slurry.
4. The process of Claim 1 in which said slurry has a pH in the range of about 6 to about 12.
5. The process of Claim 1 in which said slurry has a pH in the range of about 9 to about 11.5.
6. The process of Claim 1 in which said N-butoxycarbonyl-O-alkylthionocarbamate is N-butoxycarbonyl-O-ethylthionocarbamate.
7. The process of Claim 1 in which said N-butoxycarbonyl-O-alkylthionocarbamate is N-butoxycarbonyl-O-butylthionocarbamate.
8. The process of Claim 7 in which said N-butoxycarbonyl-O-butylthionocarbamate is selected from the group consisting of N-isobutoxycarbonyl-O-isobutylthionocarbamate and N-butoxycarbonyl-O-isobutylthionocarbamate.
9. The process of Claim 1 in which said N-butoxycarbonyl-O-alkylthionocarbamate is N-butoxycarbonyl-O-hexylthionocarbamate.
10. The process of Claim 1 in which said ore comprises a metal selected from the group consisting of copper, lead and zinc.
11. The process of Claim 10 in which said N-butoxycarbonyl-O-alkylthionocarbamate is selected from the group consisting of N-isobutoxycarbonyl-O-ethylthionocarbamate, N-butoxycarbonyl-O-isobutylthionocarbamate, N-isobutoxycarbonyl-O-isobutylthionocarbamate, and N-isobutoxycarbonyl-O-hexylthionocarbamate.
