A good foundation saves the cost of dust removal and destocking of coal during subsequent combustion and chemical treatment. At present, gradient magnetic separation method, ultrasonic or microwave method, electrochemical treatment method, etc. are mostly used for desulfurization. These treatment methods have a greater impact on the environment, consume large amounts of water, and sometimes have higher temperatures.
