Fujian Qingliu non-aluminum ore extraction alumina project started

Fujian Qingliu Jiahua Mining and Smelting Co., Ltd. invested 35 million yuan to build electro-reduced andalusite ore-rich aluminum slag extraction alumina project started recently.
According to reports, the use of this technology will not only increase the grade of alumina extracted by 30%, but also the use of andalusite, kyanite, sillimanite, kaolin, fly ash and coal gangue to expand into aluminum resources. The use of non-bauxite and industrial waste residue resources to extract alumina is equivalent to expanding China's aluminum resources 20 times.
Bauxite is the main raw material for processing alumina, and alumina is the main raw material for producing primary aluminum. The technology for extracting alumina from andalusite ore is based on the carbon-thermal reduction method of the Beijing University of Aeronautics and Astronautics with proprietary intellectual property rights and is based on the technology of aluminum-rich slag preparation. It has established a unique industrial waste or non-bauxite extracted alumina in China. Technical system and realize industrialization.
