氟硅酸钠泥浆是冰晶石厂用氟氢酸生产氟化盐过程中,在氟氢酸精制脱硅时产生的一种中间产品。用纯碱分解这种泥浆加工制成氟化钠。为了提供优质氟化钠,把泥浆在间断作业制度下分解3～5小时。获得的氟化钠大部份是粗晶粒的,容易在液体介质中用分级的方法
Sodium fluosilicate slurry is an intermediate product produced by desulphurization of hydrofluoric acid in the process of producing fluoride salt by hydrofluoric acid from cryolite plant. Soda ash decomposition of this mud processing made of sodium fluoride. In order to provide high-quality sodium fluoride, the mud is decomposed for 3 to 5 hours under intermittent operation. Most of the sodium fluoride obtained is coarse-grained and easily fractionated in a liquid medium
