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: 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 preparing a sodium super ionic conductor solid electrolyte by low-dimensional crystallization belongs to a field of energy materials. The method is based on the theory of negative ion coordination polyhedron growth unit, and uses low-temperature plasma as a protective gas of a spray drying equipment. While evaporating the solvent in a sodium super ionic conductor solid electrolyte precursor slurry, plasma active groups modify the particle surface of the sodium super ionic conductor solid electrolyte precursor particles in-situ. A free space dimension of crystal growth in the crystallization process is reduced, and directional growth of crystals in the solid phase sintering process is induced. Secondly, the dispersion stability of the sodium super ionic conductor solid electrolyte precursor particles is improved. Compared with the traditional high-temperature solid-state sintering process, the method has the advantages of fast crystallization speed, high crystal purity and integrity, good compactness, and uniform particles.
