Abstract: Disclosed is a device for continuous treatment of materials containing volatile components, which belongs to the field of pyrometallurgical equipment. The device includes a feeding unit, a heating unit, a slag raking unit and a slag collecting unit. The feeding unit is configured to feed the materials with a push rod or in a spiral mode. The heating unit is provided with a square furnace body, and a first slag raking port is provided in the lower part of the furnace body. The slag collecting unit is provided with a slag discharging port at the lower portion thereof, is provided with a slag smashing port at the sidewall thereof, and is provided with a viewing port at the top thereof. The slag collecting unit and the heating unit are connected through a pipeline, thus achieving the pressure balance of the whole device during operation.

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.
