Summary: | The invention relates to a method for roasting a molybdenum concentrate. The method comprises the steps of mixing a certain amount of sodium sulfate into the molybdenum concentrate, then forming balls and roasting; performing alkaline leaching on calcine; performing ion exchange adsorption on molybdenum leachate, then performing liquid crystallization to obtain sodium sulfate, and returning the sodium sulfate to serve as a molybdenum concentrate roasting additive; performing molybdenum concentrate ball forming by using a liquid after crystallization. By adopting the method, the chemical dosage of molybdenum calcine alkaline leaching and the production cost can be greatly reduced; moreover, the sodium sulfate obtained through liquid crystallization after the ion exchange adsorption during a molybdenum extraction process flow and the liquid after crystallization can be fully used for performing molybdenum concentrate ball forming, and the wastewater treating amount can be reduced. |
