Key trends in iron ore, alumina, steel and scrap and metallurgical coal, plus a view on what the next few months could bring, from supply and demand shifts, to new arbitrages, and to quality spread fluctuations.
Aluminum recovery from coal fly ash by high temperature ...
Removal of gangue materials, principally silica and alumina, from a magnetically-separated, iron-rich fraction of bituminous coal fly ash shows promise of yielding an iron ore grade concentrate. As separated, the iron-rich fraction contains 65 to 75 weight percent iron oxides or about 50% of the iron originally in the ash.
Comprehensive Extraction of Silica and Alumina from High ...
Large amounts of high-alumina coal gangue (HACG) with the main mineral of kaolinite [Al 2 Si 2 O 5 (OH) 4] are generated during the mining and washing of this coal. Meanwhile, the alumina production in China was ~ 73 million tons with bauxite consumption of 160 million tons in 2019, but the China's bauxite reserve is only ~ 1 billion tons [ 15 ].

Processing of Coal Fly Ash for the Extraction of Alumina ...
Abstract Coal fly ash is a lightweight incombustible particulate generated during coal combustion. Alumina content in the fly ash is present in the mullite phase, and its high stability calls for alternative processing for conversion to reactive phase before leaching. Mechanical activation with sodium hydroxide was found unsatisfactory for the breakdown of mullite structure, whereas the ...

Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.
