Apart from reducing other impurities through filtration, the purity of soda ash is subsequently improved mainly by controlling the calcination temperature to minimize the loss on ignition
Calcium and magnesium are reduced through brine purification; iron is reduced through the carbonation process; sodium is reduced through filtration; moisture is reduced through calcination, etc. The iron remover reduces wear or the detachment of iron particles or pieces on conveying equipment. There are many methods.
