nickel, primary, from platinum group metal production

Contents

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 South Africa (ZA). 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.

includedProcesses The module includes a mining and a beneficiation step with the mining infrastructure and disposal of overburden and tailings. Subsequently it includes the metallurgy step with the disposal of slag, the infrastructure and the separation of the co-products nickel and copper, and the refining step yielding the desired PGM-mix inclusively the refining infrastructure. Production, application and emissions of most agents used in beneficiation and metallurgy are also included.

geography

location ZA
text Some agents used like lime or sodium cyanide originate from data sets valid for Switzerland or Europe. Processes like blasting and transport originate from data sets valid for Switzerland or Europe.

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 ZA a electric arc furnace with a Søderberg electrode system and a Pierce-Smith-Converter is used. sulphur dioxide in the off-gas is recovered producing sulphuric acid. The separation of non ferrous metals is done hydrometallurgically, the refining by selective precipitation. Allthough electricity production in ZA is mainly coal based, the UCTE production mix is inventoried.
