Summary: | The invention discloses a method for recovering molybdenum and sulfur from molybdenum tailings and preparing molybdenum-silicon fertilizer by using the molybdenum tailings as raw materials. The methodcomprises the steps that molybdenum concentrates and sulfur concentrates are recovered through flotation, heavy metal ions in the tailings are removed through flotation again, then the tailings withthe heavy metal ions removed are mixed with dolomite, and the raw materials of the silicon fertilizer are prepared according to the proportion of each component of a silicon fertilizer raw material list, and calcining and water quenching are carried out to obtain the finished silicon fertilizer. According to the method, the external discharge amount of the tailings can be decreased from the source, and meanwhile, the method has profound significance in increasing the comprehensive utilization rate of mineral resources in China, decreasing the discharge amount and promoting the agricultural development.
