A few days ago, the Chinalco Shanxi New Material Technology R&D Center initiated a demonstration project for the comprehensive utilization of secondary aluminum ash to achieve a single trial run, which is expected to be officially put into operation this month.
Aluminum ash is the scum produced in the production process of aluminum products. Secondary aluminum ash is the residue left after the scum is extracted from the metal aluminum. Because of its greater environmental hazard, it is included in the “National Hazardous Waste List”. If contracted to a foreign commission for disposal , Need to pay a huge amount of disposal costs. In order to realize the comprehensive utilization of resources, after nearly two years of hard work, the center has carried out detailed investigations and repeated demonstrations from the preliminary process plan research, process condition experiment, project approval to construction. In the process of implementation, the center overcomes difficulties such as high temperature, tight time, and few personnel, successfully extracting useful substances in secondary aluminum ash, and finding an economically feasible way to use waste.
After the implementation of the project, it can not only realize resource utilization, open up new profit growth points for the company’s transformation and upgrading, but also provide secondary aluminum ash solutions for Chinalco and the aluminum industry.
