| titleOfInvention | Method for preparing aluminum-silicon alloy from low-grade aluminum resources |
| abstract | The invention belongs to a method for comprehensively utilizing resources, and particularly relates to a method for preparing an aluminum-silicon alloy from low-grade aluminum resources. Iron is removed through the circulation of ammonium bisulfate, and simultaneously, lost alumina is effectively recovered, and the ammonium bisulfate is recycled, so that the cost is low; and no waste residue and water are discharged in the process, so that the process is more environment-friendly. The invention aims to remove the ferric oxide and the calcium oxide, and the cost is greatly lower than that of respectively purifying the aluminum oxide and the silicon oxide. The reaction system of the invention is a weak acid and alkaline system, the equipment is easy to solve, and the invention is beneficial to industrialization. |
