Abstract

A mineral separation process includes wet-grinding the ore to liberation of minerals, oxidizing the slurry using air, hydrogen peroxide or other oxidants and floating the valuable minerals at a pH between about 9.0 and 10.0 with a xanthate as collector, and a combination of a polyamine and a sulfur containing species as depressants for arsenide minerals. This depressant suite effectively depresses the flotation of arsenide minerals with no effect on the flotation of the valuable minerals.

Claims (26)

1. A flotation process for selectively recovering valuable metals from an ore comprising the steps of:
wet-grinding the ore into a slurry, adjusting the pH of the slurry to a preset value by the addition of reagents, providing an oxidizing environment to the slurry, adding a reagent suite of a polyamine and a sulfur-containing species to the slurry for depressing flotation of arsenide minerals, readjusting the pH of the slurry to a preset value by the addition of reagents adding a collector and a frother at effective dosages to the slurry to float valuable minerals to be recovered.
2. A process according to Claim 1 wherein the pH of the slurry is about 9.0 to 10Ø
3. A process according to Claim 1 wherein the pH of the slurry is adjusted by the addition of lime.
4. A process according to Claim 1 wherein the oxidizing environment is created by utilizing an oxidant selected from at least one of the group consisting aeration, the addition of hydrogen peroxide, and the addition of permanganate ion.
5. A process according to Claim 1, wherein said polyamine is selected from at least one of the group consisting of ethylene diamine, 1,3-diaminopropane, (2-aminoethyl)-2-aminoethanol, histidine, diethylenetetramine, triethylenetetramine, and any other polyethylenepolyamines in which the number of ethyleneamine units is equal to or greater than that in diethylenetriamine.
6. A process according to claim 1, wherein said sulfur containing species is selected from at least one of the group consisting of thiosulfate, sulfides, hydrosulfides, polysulfides, sulfites, metabisulfites, hydrosulfites, dithionates, tetrathionates, sulfur dioxide, and mixtures thereof, wherein a cationic part of said sulfur containing species consists of hydrogen, sodium, potassium, ammonium, calcium, and barium.
7. A process according to Claim 1 wherein the polyamine and sulfur containing species are provided in a ratio ranging from about 1:1 to 1:8 and most preferably from about 1:1 to 1:4.
8. A process according to Claim 1 wherein the collector is selected from at least one or more of the group consisting of xanthates, phosphine-based compounds, dithiophosphonates, alkyldiphosphates, thionocarbamates, thiourea or other conventional sulfhydryl collectors.
9. A process according to Claim 1 wherein the frother is polypropylene glycol methyl ether.
10. A process according to Claim 1 wherein the slurry contains about 20% to 45% solids by weight.
11. A process according to Claim 1 wherein the slurry has a temperature between about 5°C and 35°C.
12. A flotation process for selectively recovering high grade nickel and copper metal concentrates from nickel-copper ore comprising the steps of:
wet-grinding the nickel-copper ore into a slurry, adjusting the pH of the slurry to a preset value with the addition of reagents, providing an oxidizing environment to the slurry, adding a reagent suite of a polyamine and a sulfite to the slurry for depressing flotation of arsenide minerals, readjusting the pH of the slurry to a preset value with the addition of reagents and adding a collector and a frother at effective dosages to the slurry to float the nickel and copper metals to be recovered.
13. A process according to Claim 12 wherein the slurry includes pentlandite, chalcopyrite, pyrrhotite, gersdorffite, cobaltite and niccolite and siliceous gangue minerals.
14. A process according to Claim 12, wherein the arsenide minerals to be depressed are gersdorffite, niccolite and cobaltite.
15. A process according to Claim 12 wherein the pH of the slurry is about 9.0 to 10Ø
16. A process according to Claim 12 wherein the pH of the slurry is adjusted by the addition of lime.
17. A process according to Claim 12 wherein the oxidizing environment is created by utilizing an oxidant selected from at least one of the group consisting of aeration, the addition of hydrogen peroxide, and the addition of permanganate ions.
18. A process according to Claim 12 wherein the reagent suite for depressing arsenide minerals is an effective ratio of triethylenetetramine to sodium sulfite.
19. A process according to Claim 18 wherein the triethylenetetramine to sodium sulfite ratio is about 1:2 by weight.
20. A process according to Claim 12 wherein potassium amyl xanthate is added as the collector.
21. A process according to Claim 12 wherein the frother is a polypropylene glycol methyl ether.
22. A process according to Claim 12 wherein an effective dosage of the collector is provided and determined by pentlandite, chalcopyrite and pyrrhotite content in the nickel-copper ore.
23. A process according to Claim 12 wherein an effective dosage of the frother is provided to produce a Cu-Ni bulk concentrate of high grades at maximal copper and nickel recovery.
24. A process according to Claim 12 wherein froth is generated by rising air bubbles through an introduction of air to the slurry.
25. A process according to Claim 12 wherein the slurry contains about 40% solids by weight.
26. A process according to Claim 12 wherein the slurry has a temperature between about 23°C.
