Silica Sand Processing Line

When kaolin contains pyrite and organic matter, it often makes the minerals gray. These substances are difficult to be removed by pickling and reduction methods, so it is necessary to use oxygen PTMS magnetic separator to remove iron for bleaching. Iron removal by oxidation is a strong oxidizing agent that oxidizes pyrite in a reducing state into ferrous ions soluble in water.

PTMS magnetic separator

 
Dark organic matter is oxidized to a colorless oxide that can be washed away. The oxidants used in the oxidation process of PTMS magnetic separator are sodium hypochlorite, hydrogen peroxide, potassium permanganate, chlorine gas, ozone, etc. Effect of pulp concentration. When the dosage of reagent is constant, the bleaching effect of iron removal decreases with the decrease of pulp concentration. If the concentration is too high, because the product is not washed, too many residual pharmaceutical ions after filtration will also affect the product performance.

what is magnetic separation？

 
Effect of bleaching time. The longer the time, the better the effect of removing iron from PTMS magnetic separator. At the beginning, the reaction speed is fast, and then it is slower and slower. The reasonable and economical bleaching time needs to be determined by test.
