Based on the review of current situation of glass-ceramics made by tailings,a systematic analysis on blending principle and balance calculation process of raw materials for glass-ceramics made by tailings was put forward.On the basis of this principle,a blending optimizing system for glass-ceramics made by tailing was developed.In addition,the function and application(for glass-ceramics made by remaining iron ore tailings) of the blending optimizing system were also introduced.
