Title: Treatment of arsenical waste liquor - with e.g. hydrogen sulphide at defined temp. to give high density agglomerate
Inventor: TERASAKI HIROKAZU
IPC: C01G28/00
Filed: 1978-03-23
Abstract: Method of treating waste liquor contg. arsenic and arsenic sulphide sludge involves treating the sludge by a hydrothermic process at a temp. not less than its softening point and not greater than its m.pt. Suitably either (1) during the deposition of arsenic sulphide, a sulphurating agent is added to the liquor, in the presence of SO2; or (2) the sulphurating agent is added after degassing of the waste liquor. The softening and melting points can be determined from a figure in which both are plotted against the S:As molar ratio. The sulphurating agent is pref. H2S, NaHS, or a metal sulphide e.g. of Na or Fe. Method effects isolation of As as its sulphide. It permits an increased density of the agglomerated mass. The mass can be put into any desired form. Storage space can be reduced. The temp. during treatment can be reduced by sulphurating in the presence of SO2, but without any important loss in density. No addn. of sulphur is necessary.
