According to a recent announcement from the Chinese Academy of Sciences' Institute of Geochemistry, a research team led by Li Yang has discovered, for the first time, the mineral bornite with evaporative deposition characteristics in the Chang'e-5 lunar regolith samples. This research finding was recently published as a cover article in Science Bulletin. The results provide direct evidence of vapor deposition of sulfides on the lunar surface, revealing the migration of gaseous components caused by lunar impact processes and their typical modification effects on lunar surface materials. The discovery of bornite in the Chang'e-5 lunar regolith also broadens our understanding of the complex mineral composition of the lunar surface.
Schematic diagram of the evaporative deposition mechanism of bornite in lunar regolith
Bornite (chemical formula: 4Cu2S·CuS) usually occurs as fine-grained aggregates, with common octahedral cleavage. It is malleable. In bornite, chalcocite or covellite lamellae can be produced by the separation of solid solutions. Bornite is often closely associated with various copper sulfides. In the secondary enrichment zones of sulfide deposits, fine-grained bornite often replaces other sulfides along edges or fractures. It is mainly found in low-to-medium temperature hydrothermal, leaching, and sedimentary deposits, and is a type of non-ferrous metal mineral.
The JPXRT intelligent ore sorting system is applicable to all types of minerals, including non-ferrous metal ores (tungsten, antimony, lead, zinc, nickel, molybdenum, tin, copper, etc.), non-metal minerals (fluorite, limestone, quartz, calcite, phosphate, magnesite, etc.), ferrous metal ores (iron, chromium, manganese, etc.), precious metal ores (gold, silver, etc.), and building materials (building material sorting and waste classification), and is independently developed and produced by Hunan Jumper Technology Co., Ltd. After more than 6 years of market use and technological iteration and updates, it has been frequently recognized in ore sorting examples of non-ferrous metal ores, non-metal ores, ferrous metal ores, and precious metal ores.
