A Different Approach to Heavy Media Circuits

摘要

For a little more than 10 years now, Beijing Guohua Technology Group (BGTG) has been installing heavy medium cyclones and flotation systems in preparation plants processing Chinese, Russian, Indian and Mongolian coking coals. The systems are popular and, as of April 2011, more than 430 plants (or 70% of the Chinese coking coal washing capacity), were using Guohua technology. The systems integrate multiple technologies based on two types of core products: a gravity-fed, heavy-media cyclone and an associated heavy media cyclone for fine coal separation. The company markets a novel flotation system as well. The driving force behind Guohua Technology (pronounced: gwo-wa) is Founder, Chairman and Chief Engineer, Zhao Shuyan. During his career in Chinese coal preparation, he patented this equipment and other technologies. While China privatized its coal industry, Zhao's BGTG has flourished. BGTG is now looking to expand in the U.S. and the company recently appointed Sam Johnson president of Guohua Technology Corp. (GTC), which is based in Lexington, Ky. Johnson has accepted the challenge of introducing BGTG's technology and equipment into the U.S. coalfields, particularly coking coal operations in Appalachia. "We have held several meetings with interested parties after GTC formally introduced itself to the U.S. coal business at Coal Prep 2011," Johnson said.
