| titleOfInvention | A kind of method containing bauxite resource comprehensive utilization |
| abstract | The invention belongs to the method for comprehensive utilization of resources, particularly relate to a kind of method containing bauxite resource comprehensive utilization, comprise the steps: that ammonium sulfate heats by (1), decompose, produce monoammonium sulfate and ammonia; (2) mix containing the monoammonium sulfate of bauxite resource with step (1), and add water or washing lotion; (3) carry out solid-liquid separation and washing after reaction cooling, obtain the solution of aluminum ion and iron ion and excess sulfuric acid hydrogen ammonium solution and high white residue; (4) step (3) gained solution is added ammoniacal liquor or ammonia, obtain aluminium hydroxide and ferric hydroxide precipitate and ammoniumsulphate soln, then carry out solid-liquid separation washing; (5) ammoniumsulphate soln that step (4) obtains is carried out evaporative crystallization separation, obtain ammonium sulfate solids; (6) aluminium hydroxide step (4) obtained and ironic hydroxide solid is treated obtains metallurgical-grade aluminum oxide and high scum.Energy consumption of the present invention is low, and the leaching yield of aluminum oxide and iron is high, and effective constituent enrichment degree is high, and production cost is low. |
