, in which the trivalent arsenic (As2O3) vapor forms [5,6]. Moreover, the arsenic-bearing dusts still contain certain useful metal elements, such as lead, antimony, copper and indium [7]. Unfortunately... subsequent processing [20]. Thus, it is important to develop a novel technology for selective extraction of arsenic and recovery of the valuable metal elements. With the presence of sulfide ions [21......
