Abstract
The utility model provides a gangue recycling sulfur-iron separating mineral dressing system. The gangue powder is transported into a batch hopper by a hopper, a magnetic vibration feeder and a belt conveyer. The material diluted by adding water goes into a primary magnetic separator, a second-grade magnetic separator, a third-grade magnetic separator, a fourth-grade magnetic separator, a fifth-grade magnetic separator and a sixth-grade magnetic separator in sequence to be sorted and separated. The sorted and separated gangue flows into a workshop gangue groove. The substance containing magnet flows into an iron powder precipitation tank to complete the sorting and separating process of the iron ore powder. The gangue groove is communicated with a powdered sulfur precipitation tank. The powdered sulfur is precipitated inside the tank due to the great specific gravity thereof. The low-grade powdered sulfur after separated by the powdered sulfur precipitation tank performs the flotation by a flotation device and flows into a fine powdered sulfur precipitation tank to be precipitated, and fine powdered sulfur is obtained, therefore, the powdered sulfur dressing process is completed. The gangue recycling sulfur-iron separating mineral dressing system is particularly suitable for the large-scale gangue recycling work and solves the problem of resources waste. The gangue recycling by adopting the system has low cost, high output value, the production cost only accounts for about 10 percent of the output value and the profit accounts for about 90 percent.
