| 摘要 | A method of concentrating and recovering spodumene from an aqueous pulp or slurry by conditioning the pulp with an aliphatic primary beta-amine having from seven to 15 carbon atoms (preferably as a soluble acid salt), subjecting to flotation at a pH of about 8-10 to float off the impurities, and recovering the spodumene concentrate as residue. | ||||||
| 权利要求 | 2. The method of claim 1 wherein a dispersant selected from starch and dextrin is present during conditioning. 3. The method of claim 1 wherein the beta-amine is added in the form of a water-soluble acid salt. 4. The method of claim 3 wherein the acetate salt of 2-aminononane or 2-aminodecane is used. 5. The method of claim 3 wherein the salt is added in amounts from about 0.02 to 0.2% by wt. of the solids. 6. The method of claim 1 wherein the pH of the conditioned pulp is about 9.5-10. 7. The method of claim 1 wherein the recovered spodumene fraction is subjected to a high intensity wet magnetic separation step. 8. The method of claim 1 wherein the amine is 2-aminononane or 2-aminodecane. 9. The method of claim 1 wherein the amine is a mixture of 2-aminodelane and 2-aminononane. |
