2form Na
2(HgCl
4) double salt and by wash-out, then with formaldehyde, this double salt is reduced into mercury metal, reclaim, the Induction refining processed adsorbs HgCl again
2, for the production of.Wet method is easy to start, and equipment requirements is not high, implements than being easier to, but its HgCl
2the rate of recovery can only reach 60%, so the normal Induction refining adopted reclaims be generally dry method.In Dry recovery technique, mercury vapour condensate recycling device is the vitals that mercury reclaims, and the condensation effect of conventional condensing works is poor.
