Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is gold, a high-purity precious metal element, presenting a golden-yellow color, with extremely high ductility and toughness, outstanding chemical stability, and being not easily corroded or oxidized, making it a basic material and important strategic resource essential for the national economy, national defense industry and scientific and technological development. This product is extracted and prepared through a halogen leaching process, with the upstream raw material being oxidized concentrate; downstream it is mainly used in jewelry processing and precious metal value preservation and reserve fields, followed by application in electrical and electronics (bonding gold wire, connectors, gold plating layers), aerospace and precision instrument manufacturing, dental medicine, and chemical catalysis. High-purity gold and gold-based materials also play an irreplaceable key role in emerging low-carbon frontier technologies such as highly reliable microelectronic packaging, optoelectronic devices, and selective catalysis. The dataset includes the main raw and auxiliary materials, energy and waste of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the halogen leaching process, covering the process of obtaining gold from oxidized concentrate.
Process Description
Gold is a golden precious metal with extremely high ductility and toughness, outstanding chemical stability, and is not easily corroded and oxidized. It is considered a basic material and an important strategic resource necessary for the development of the national economy, defense industry, and science and technology. Gold is mainly used in jewelry and value-preserving reserves, followed by electronic and electrical fields (bonding gold wires, connectors, gold plating), aerospace and precision instruments, as well as dentistry and chemical catalysis. At the same time, high-purity gold and gold-based materials also play an irreplaceable key role in emerging low-carbon cutting-edge technologies such as highly reliable microelectronic packaging, optoelectronic devices and selective catalysis.

Technology comment
The oxidized concentrate is first sent to the halogen leaching reactor, where gold is leached with chlorine or bromine under acidic conditions to generate a gold-rich pregnant solution (PLS); the residue after leaching is separated and washed, and the washing liquid is recycled; the gold-rich pregnant solution is adsorbed on silica gel to recover gold, and the gold solid is obtained through filtration.
