Abstract

1368127 Mercury recovery Y KUMIHIGASHI 24 Nov 1971 [26 Nov 1970] 54645/71 Heading C1A [Also in Division C7] A process for the recovery of mercury from mercury containing sludges, comprises dissolving the sludge in a mineral acid and at a pH of 3À0 to 7À0, contacting the resulting solution with a chelate forming resin containing in its functional group sulphur or oxygen chemically linked to nitrogen. Such sludges as treated by the process are formed in mercury processes for electrolysis of alkali metal salt in aqueous solution. Preferred forms of the invention use hydrochloric acid in a solution pH of 3À5 to 5À5 and also the sludge is filtered prior to the addition of acid.
