| titleOfInvention | With the method for the insoluble rich potassium aluminium mineral production metallurgy level sandy alumina of compound salt treatment |
| abstract | The present invention relates to a kind of method with the insoluble rich potassium aluminium mineral production metallurgy grade aluminum oxide of compound salt treatment, including：(1) calcination process is carried out after insoluble rich potassium aluminium mineral is mixed with complex salt, roasting material goes out through water logging, solid 1 and liquid 1 is obtained after separation of solid and liquid；(2) add after calcium oxide or calcium hydroxide and stir into liquid 1, solid 2 and liquid 2 are obtained through separation of solid and liquid；(3) aluminium hydroxide or alumina seed are added into liquid 2, CO is passed through 2 Until pH value of solution obtains Al (OH) to about 9~10 through separation of solid and liquid 3 Solid and liquid 3；(4)Al(OH) 3 Solid obtains metallurgical-grade aluminum oxide in about 950~1100 DEG C of temperature lower calcinations. |
