The project “Comprehensive Utilization and Development of Fly Ash in Zhungeer Mining Area†completed by Dr. Pan Aifang of Chang’an University was recently identified by the expert group. The application of this result can increase the comprehensive utilization rate of fly ash to more than 90%, and the economic benefits of the two products, alumina and silica, can be considerable.
Most of the traditional processes convert fly ash into building materials, which not only wastes valuable aluminum and rare earth resources from fly ash and ash, but also has a high cost. For this purpose, Shenhua Group Zhungeer Energy Co., Ltd. and Chang'an University jointly tackled the problem. After more than one year, it has obtained the aluminum oxide extraction process of the pulverized coal furnace pulverized coal ash and the carbon dioxide recovery process in the waste of the sintering furnace. Research and research results on the use of fly ash for the extraction of alumina waste slag as a building material and other seven scientific research results. They extracted alumina from pulverized coal, furnace powder and coal ash in a laboratory environment and separated the silica by silica gel to form a water-acid combined step-by-step elution method for extracting alumina and co-production of silica gel. New craftsmanship.
At present, this new technology is being further improved and promoted.
