Description

Location: GLO - Global
The multioutput-process 'platinum group metal production, primary' delivers the co-products 'platinum, primary, at refinery', 'palladium, primary, at refinery', 'rhodium, primary, at refinery', 'nickel, primary, from platinum group metal production' and 'copper, primary, from platinum group metal production' in the Russian Federation (RU). The module is designed for the use of the metal in technical systems, where it plays a minor role like the use in manufacturing of electronic or technical chemistry using certain catalysts. It is not to be used if the impact of the PGM within the modelled process in scope is considered to be high. In such cases, a more detailed analysis depending on scope and allocation procedures has to be conducted. The data used is mainly based on a LCA study for autocatalysts in Germany.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

Mining is done underground, followed by beneficiation trough flotation where considerable amounts of agents are added. Overburden and tailings are disposed on the mining site and partly refilled. In RU a Outokumpu flash furnace followed by a Pierce-Smith-Converter is used. The resulting nickel matte is treated by elektrorefining. No recovery of sulphur dioxide in the off gas. The refining is done by selective precipitation, using data from the ZA process as proxy. For electricity mix the UCTE production mix is inventoried
