Abstract

PURPOSE: To conduct Hg and Se recovery from sludge with high yield by a method wherein sulfuric acid sludge which contains Hg and Se is treated by attrition method in solution made acidic by sulfuric acid and then processed by floatation selection.
CONSTITUTION: Sulfuric acid sludge which contains Hg and Se is formed in preparing sulfuric acid from SO2 gas produced in non-ferrous metal smelting process. Such sludge is treated with attrition in acid sulfuric solution and subject to flotation in acid at pH3 or less. At this time, MIBC is used as foaming agent and Aerofloate No.208 as collector. Selenide of Hg is recovered as floatation concentrate in a high yield. Settled tailing, if it contains 0.004% or more Hg concentration, is treated by sulfurizing using a sulfurizer such as hydrogen sulfide, sodium sulfide, sodium thiosulfate. The tailing is then retreated by floatation to form sulfide floatation material and tamade as floatation repeat material, together with refined tailing produced in floation cleaning.
