据《Mining Engineering》报道:美国匹茨堡能源技术中心研究和开发了高效浮选柱技术并实现商业化,商品名为“Microcel”。这种微气泡浮选柱技术具有显著的优点,能高效浮选细粒煤甚至是超细粒煤。该工艺产生的微气泡,能排除煤浆中的矿物质,而浆液中的 According to “Mining Engineering” report: The United States Pittsburgh Energy Technology Center has researched and developed high-efficiency flotation column technology and commercialization, under the trade name “Microcel.” This micro-bubble flotation column technology has the obvious advantages of high-efficiency flotation of fine coal or even ultra-fine coal. The process produces microbubbles that remove the minerals in the slurry while in the slurry
