Abstract Gallium (Ga) is known as the backbone of the electronics industry, but its independent mineralization is rarely found in nature. The discovery of large Ga-bearing coal deposits suggests that the coal-bearing series can be used as the main source for the future development and utilization of Ga, and the organic matter of coal may play an ...

Study on Coal’s Green Mining Technology Roadmap of Jurassic Coalfield in Northern Shaanxi
Advanced Materials Research, 2014Jurassic coalfield in northern Shaanxi is a typical ecologically fragile area. In recent years, with the rapid development of coal mining industry in this area, the environmental problems were caused by coal mining have become so serious that threat seriously to the sustainable development of northern Shaanxi. In this paper, the research team use multi-

This paper describes the organic geochemical characteristics and their roles on barium enrichment in the No. 2 Coal from Huanglong Jurassic Coalfield, China. A total of 18 bench samples were taken from Huangling Mine 2. The average content of barium (3701 mg/kg) was about 23 times higher than that of common world coals.
