Description
The product represented by this dataset is gold, a high-purity elemental precious metal. It is golden-yellow in color, possesses extremely high ductility and toughness, and exhibits outstanding chemical stability, being resistant to corrosion and oxidation. It is a fundamental material and important strategic resource essential to the national economy, the defense industry, and the development of science and technology. This product is extracted through a cyanide leaching recovery process, with gold-loaded carbon as the upstream feedstock. Downstream, it is mainly applied in jewelry processing and precious-metal value preservation and reserves, and is also widely used in electronics and electrical engineering, aerospace, precision instrument manufacturing, dental and medical applications, and chemical catalysis. High-purity gold and gold-based materials also have irreplaceable and critical application value in low-carbon frontier technology fields such as high-reliability microelectronic packaging, optoelectronic devices, and selective catalysis. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants 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 cyanide leaching recovery stage, covering the process of obtaining gold from gold-loaded carbon.
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 gold-loaded carbon is eluted to desorb the gold adsorbed on the carbon surface from the carbon to form a concentrated gold solution; then, the gold solution is sent to the electrolytic cell, and the gold is deposited on the cathode through electrowinning to form electrolytic gold.
