Distribution, occurrence, and enrichment of gallium in the Middle Jurassic coals of the Muli Coalfield, Qinghai, China

Journal of Geochemical Exploration, 2018
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 ...
