Abstract

PURPOSE: To improve the reactivity of gaseous hydrogen sulfide and arsenic and remove arsenic efficiently by introducing the gaseous hydrogen sulfide into ≥1 of tightly closed vessels having a gas-liquid contact function, and causing the same to react with liquid contg. arsenic in one or multiple stages.
CONSTITUTION: An aqueous sodium hydrosulfide soln. and sulfuric acid are caused to react in a hermetically closed generator 1, and the produced gaserous hydrogen sulfide is stored in a gas holder 7. This gaseous hydrogensulfide is introduced into a simple gas-air contact device, for example, a hermetic vessel 2 provided with spraying or dispersing plates for liquid, packings, trays, etc., where it is allowed to react with the liquid contg. arsenic. The liquid having completed the reaction is separated of arsenic sulfide by a solid-liquid separator 3 via a settler 8, after which it is removed of the hydrogen sulfide remained therein through a deaerator 4 and further it is passed through a recovering process for nickel and the like according to need. In general, it is recirculated to a copper electrolysis process.
