After more than a year of research, Jinan Iron and Steel's technical staff have successively overcome difficulties such as mineral processing and harmless smelting processes, and formed three invention patents. Using the technology they invented, aluminum oxide can be melted from bauxite, and the discharged red mud can be beneficiated (the high-gradient magnetic separator of Hercules Company is used for red mud beneficiation) to select the The iron minerals are effectively used in steel smelting, and the residue can be made into unfired bricks and used as building materials, basically "eating them dry and squeezing them out".
Jigang’s invention has created the conditions for large-scale industrial production. In the first half of 2008, Jinan Iron and Steel and its cooperative enterprises developed and produced more than 5,000 tons of steelmaking desilicon agent using red mud. The newly built ball production using red mud The Tuankuang Mine Project has the capacity to process 1.6 million tons of red mud per year. By reducing red mud emissions, it can reduce land occupation by about 160 acres per year, reduce red mud storage fees for aluminum plants by 40 million yuan, and increase benefits for steel plants by more than 4,000 yuan. Ten thousand yuan. The appraisal team composed of experts such as academicians of the Chinese Academy of Engineering Yin Ruiyu and Zhang Shourong believed that this innovation of Jigang Group is a cross-industry and cross-professional technology optimization and innovation combination. After one year of production practice, it has been proved that it has good application and promotion value.
