Latest Patents

Qingchun Yu holds a patent for a "Method for comprehensively processing noble lead." This method utilizes two instances of vacuum distillation to achieve an open circuit for arsenic, lead, antimony, and bismuth. It allows for the high-efficiency enrichment of precious metals such as gold and silver. The process results in the production of elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy, and a copper alloy. These alloys are further refined through oxidation refining, electrorefining, and chlorination refining to yield refined lead, refined antimony, antimony trioxide, electrolytic silver, and electrolytic copper. The entire process boasts advantages such as high metal direct yield, low energy consumption, a short flow chart, and simple equipment. Notably, vacuum distillation is a physical process that separates the alloys based on the difference in saturated vapor pressure between the metals, without generating wastewater, waste gas, or waste residue.
