Abstract: Provided is a method for preparing 7N tellurium, including the following steps: mixing 2N crude tellurium with concentrated sulfuric acid, and subjecting a resulting mixture to oxidation roasting to obtain a selenium dioxide vapor and a roasting residue; mixing the roasting residue with a strong base solution, and subjecting a resulting solution to electrolysis to obtain 4N electrolytic tellurium; subjecting the 4N electrolytic tellurium to vacuum distillation to obtain 5N tellurium; and melting the 5N tellurium to obtain a tellurium melt, immersing a crystallizer in the tellurium melt, and subjecting the tellurium melt to crystallization to obtain the 7N tellurium; wherein the method is performed for a total time of less than 14 days.

Abstract: Disclosed is a method for removing impurity mercury from crude selenium. The method includes: mixing a vulcanizing agent with a crude selenium slag that is crushed to not more than 200 mesh uniformly, and performing briquetting to obtain a mixed material; adding the mixed material into a sealed furnace, and subjecting the mixed material to vulcanization by heating under an inert atmosphere to obtain a vulcanized selenium; subjecting the vulcanized selenium to primary vacuum distillation, such that selenium is converted into a gas phase and collected in a form of a volatile, and generated mercury sulfide and valuable elements are enriched in a resulting residue; and subjecting the selenium to secondary distillation to further remove mercury.

Abstract: This invention presents an electrochemical metallurgical technique for extracting metals and sulfur from metal sulfides, offering an adjustable composition and mechanical properties during electrode preparation. The metal sulfide anode, submerged in an electrolyte with a cathode made of materials like titanium, copper, stainless steel, lead, zinc, aluminum or graphite, undergoes electrolysis. This process oxidizes sulfur in the metal sulfide to the anode and releases metal ions into the electrolyte, where they're reduced at the cathode. The method yields metal at the cathode and sulfur at the anode, with minimal environmental impact, low investment, and straightforward process.

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: A device is described that, while operating in an automobile configuration, causes a vehicle system of an automobile to display part of an automobile graphical user interface (GUI) while locally displaying a different part of the automobile GUI. Responsive to receiving user input for switching to a non-automobile GUI that permits access to at least some features of the device that are restricted by the automobile GUI, the device replaces the part of the automobile GUI that is locally displayed on the device with the non-automobile GUI, all while continuing to cause the vehicle system to display its part of the automobile GUI. The device accesses the at least some features of the device and responsive to receiving user input for switching back to the automobile GUI, the device replaces the non-automobile GUI with the part of the automobile GUI that was previously displayed by the device.
