A method for processing tungsten-containing materials, through ore blending, the ratio of the 0.5 power of the mass percentage of tungsten trioxide contained in the raw material to the mass percentage of silicon dioxide in the raw material is less than or equal to 0.5 to 0.8; the solid tungsten-containing material is placed in a crushing device Crush to the ideal particle size; then add the decomposition agent sodium hydroxide or sodium hydroxide solution, stir, add a small amount of water while adding the decomposition agent, and control the volume of the slurry to be 0.9 to 1.2 times that of the tungsten-containing material; control the decomposition temperature to 120 ~ 200°C, after the decomposition temperature is reached, the holding time is 2-5h; control the solution temperature after unloading at 50-100°C, add cinchonine solution dropwise, the solution of washing the press filter residue has no white precipitate, which is the washing end point, and the filter plate is unloaded to remove the slag . According to the invention, the impurity silicon dioxide in the ore can be turned from waste to treasure, and after the silicon dioxide reaches a high grade during ore blending, it becomes an inhibitor of alkaline earth metal, so that the tungsten content of the decomposed slag is less than 1%.
