Abstract: A method for comprehensively processing noble lead provided and utilizes two instances of vacuum distillation to realize an open circuit of arsenic, lead, antimony and bismuth and the high-efficiency enrichment of precious metals of gold and silver, and can obtain elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy and a copper alloy, respectively. The lead-bismuth-antimony alloy, the silver alloy and the copper alloy are processed by oxidation refining, electrorefining and chlorination refining to obtain refined lead, refined antimony, antimony trioxide, electrolytic silver and electrolytic copper, and to realize gold enrichment. The entire process has advantages of high metal direct yield, low energy consumption, short flow chart, simple equipment, etc., and vacuum distillation belongs to a physical process in which the alloy can be separated only by means of the difference in saturated vapor pressure between the metals, without generation of wastewater, waste gas and waste residue.

Abstract: The present disclosure relates to a device and method for recovering arsenic and gallium. A closed furnace body is in communication with a vacuuming pipe, and the vacuuming pipe is connected to a vacuuming mechanism. The closed furnace body includes a first furnace body, a second furnace body and a third furnace body. A first heating mechanism and a graphite crucible are arranged inside the first furnace body, the first heating mechanism being used for heating the graphite crucible. A first collection cylinder is in communication with a second collection cylinder. The device for recovering arsenic and gallium of the present disclosure is arranged with a structure for realizing directional condensation of gallium arsenide clusters and arsenic vapor, respectively, to realize high-purity recovery of arsenic and gallium.
