Review and Development of High-sulfur Coal Flotation Desulfurization Process

The direct use of high sulfur coal destroyed our environment seriously,it is necessary to develop efficient desulfurization technology.The sulfur existing state and distribution characters of high sulfur coal were introduced,the relevant principles and theories of flotation desulfurization process were discussed,the flotation desulfurization methods were profiled,to solve the key problems in the process,suggestion on desulfurization research was given.
