 In the traditional coal washing process of the coal washing plant, magnesium chloride is not used, but polyacrylamide is mostly used, but the effect of using this coal washing agent alone is not very good. And the price is relatively high. It is for the above two reasons that magnesium chloride products have been used in the coal washing process.
 
   1. The price/performance ratio has improved rapidly.
 
  2. It can remove sulfur to form MgS and precipitate to remove sulfur.
 
   3. Magnesium chloride products are good at removing fine molecules in the aqueous solution to produce flocculent precipitation.
 
  Although the traditional medicine can also produce precipitation, the combination of the precipitate is too tight, and it is not suitable to be removed after being accumulated in the precipitation pipe tank, which increases the production cost. After magnesium chloride is used in this part, flocs are formed, which can be continuously removed by flow, which reduces production costs and improves production efficiency.
