This dataset is functional for the use of tantalum as powder in capacitors of port-able electronic devices. It is not valid for the use as an alloying element in steel. Only primary production from tantalite / pegmatite ore is considered. Tantalum as by-product from tin production is not considered.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
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.


Open pit mining and beneficiation at Wodgina and Greenbushes in Australia, re-duction from pentoxide at HC Starck, Germany. Relates to state of the art technology, where purified Ta2O5 powder is reduced by magnesium vapour in a rotary kiln or a multiple hearth furnace. Production from secondary materials such as post consumer scrap is disregarded, as is the by product tantalum from tin production.
