Abstract

After mining for many years, the coal gangue piles up, not only occupies a large amount of land, but also causes serious pollution. Therefore, the treatment and utilization of coal gangue has become an important topic for coal mining and environmental protection departments. The inorganic components of coal gangue are mainly SiO₂ and Al₂O₃, followed by Fe₂O₃, generally accounting for 75%~80% of all components. Organic components are mainly composed of Carbon, Hydrogen, Oxygen, Nitrogen and organic Sulfur, accounting for 20%~25% of all components of oal gangue. In addition, the gangue also contains a small amount of Gallium, Alum, Germanium and other rare earth elements. In recent years, the research of extracting Gallium from other raw materials has developed rapidly. In order to make full use of the waste of resources, turning waste into treasure, improve the economic and social benefits, the paper adopted orthogonal experiment to explore the the gangue gallium extraction conditions. The experiments take the high-temperature acid leaching method of orthogonal experimental design experimental conditions. Acid concentration, ignition temperature, ignition time, the acid leaching temperature, leaching time and other factors on the extraction rate of gallium. After a large number of scientific comparison of the experimental conditions, to get the better conditions of the extraction of gallium that acid concentration 6mol / L, the ignition temperature of 600°C, the ignition time 0.5h, acid leaching temperature of 100°C, leaching time for 6 h. The extraction rate of 95%, provide a viable experimental conditions for the gangue gallium extraction.
