Resourcing Utilization of High Alumina Fly Ash
High-alumina fly ash in central and western regions of Inner Mongolia is a very valuable renewable mineral resource resulting from the content of Al2O3 up to 50% and some available elements, such as gallium, titanium and light rare earth. According to the resource characteristics of high-alumina fly ash and the market demand of the non-ferrous metals and chemical products in national economic development, a technique route was researched and developed, which included high-alumina fly ash as the main raw material, extraction of alumina co-generated with active calcium silicate (chemical packing) and calcium silicon slag cement clinker. It is the process characteristics that according to the development concept about circular economy, making full use of fly ash and recycling water as sewage disposal from thermal power plants, calcium carbide slag from chemical plants and other disused resources, and achieving the separation of alumina and silica and their respective resource utilization.
