The invention relates to an anorthite material and a preparation method thereof. The adopted technical proposal comprises the following steps of: according to (ZL200510019664.3) patent technology, namely a method for preparing titanium and a titanium alloy by utilizing titanium-containing furnace slag, taking molten tailings which is extracted with the titanium alloy as a raw material, adding 20 to 50 weight percent of silica, 0 to 60 weight percent of clay and 0 to 40 percent aedelforsite, and cooling a melt to obtain the anorthite material after the mixture is completely molten and a bath composition is uniform; or taking cold tailings extracted with the titanium alloy as the raw material, adding 20 to 50 weight percent of the silica, 0 to 60 weight percent of the clay and 0 to 40 percent the aedelforsite, carrying out mix grinding on the raw material and the admixture until the particle size is less than 0.1 mm, performing blank compression, and calcining the mixture at a temperature of between 1,200 and 1,400 DEG C to obtain the anorthite material. The method takes the tailings extracted with the titanium as the raw material, saves precious bauxite resources, has low cost, ensures that industrial residue is utilized with high added value, is environment-friendly and has simple process.
