Dataset description
Refining of doré bullion to refined gold metal, as the final upstream material-supply module before coin minting. This unit process is explicitly part of the gold production chain referenced for China (DOI: 10.1016/j.jclepro.2018.01.114).
Technology description
Coin finished product manufactured at plant, where the dominant upstream module (per provided primary cluster) is refined gold production from mined ore, followed by on-site minting operations to convert refined gold into coins.; Refining of doré bullion to refined gold metal, as the final upstream material-supply module before coin minting. This unit process is explicitly part of the gold production chain referenced for China (DOI: 10.1016/j.jclepro.2018.01.114).; Coin metal is plausibly precious-metal-based, so gold supply is treated as the primary compatible upstream background based on the provided primary cluster.; Coin minting/manufacturing steps are not described in the provided context; only the existence of a plant-level production mix for a finished manufactured product is used.
Geographic context
China-based refining consistent with the provided gold production LCA context (DOI: 10.1016/j.jclepro.2018.01.114). If later populated with generic/global refinery datasets, keep CN location and document dataset substitution.
