The annual meeting of Coal Ash Asia (2015) in Shuozhou, Shanxi Province, China

Abstract

The annual meeting of Coal Ash Asia was held in Shuozhou, Shanxi Province, China, from September 21st to 24th, 2015 (CAA 2015). More than 700 attendees of 300 organizations from 15 different countries attended the 4 days’ conference, exhibition and seminars. The CAA 2015 focused on the comprehensive utilization technology of powder coal ash and desulfurized gypsum, with the aim to bring researchers, managers, and industry leaders together to share knowledge and develop highest value solutions for managing and utilizing coal combustion products. High-aluminum coal, which is abundant in Shanxi and Inner Mongolia, not only contains unusually high level of Al but also has high concentrations of Li, Ga, and REY (Sun et al., 2016). These elements with high concentrations in high-Al coal are very valuable source to various industries, and therefor make perfect economic sense and add extra benefits into coal mines and power plants if they can be recovered by beneficiation processes (Sun et al., 2012). The research team from Hebei University of Engineering has taken part in the CAA 2015. They gave series of oral presentations related to the integrated extraction of lithium (carbonate) with aluminum, silicon, and possibly gallium, which represents a feasible way for the high value-added The annual meeting of Coal Ash Asia (2015) in Shuozhou, Shanxi Province, China
