Metals and minerals
Tantalum
Where it comes from, what share of a sector’s output it is, and which conflicts the model routes through it.
This page shows production, shares and inputs. It shows no death toll per tonne. The shares below say what fraction of a sector’s output this material is and what fraction of a conflict’s harm the model routes to it; multiplying either by a count of people produces a result, and a result is not published until it has a run, an uncertainty interval and a confidence grade.
- Conflict mineral — Regulation (EU) 2017/821 — supply chain due diligence for importers of tin, tantalum, tungsten and gold from conflict-affected and high-risk areas.
- Critical raw material — Regulation (EU) 2024/1252 (Critical Raw Materials Act), Annex II — the 34 critical raw materials. https://eur-lex.europa.eu/eli/reg/2024/1252/2024-05-03/eng

Harm per tonne and per euro
Harm per tonne and harm per euro are both computed. Neither is shown.
Harm per tonne of this material is defined for 2 years, 2024 to 2025: the years for which the model holds harm and world production of it has been ingested.
Both are counts of people divided by a quantity, from a run that has no uncertainty interval and no backtest yet, and nothing of that kind is published before session 21. What this page can say now is whether each is defined, and on what basis.
Which products use it
Semi-finished and finished products whose bills of materials reach this material, through every intermediate step, and how much of it one of them needs — losses included.
| Product | Needs |
|---|---|
| Printed circuit board assembly
semi-finished product |
0.100 g for one kilogram of assembled printed circuit board |
| Laptop
finished product |
0.0336 g for one laptop of 2,706 g, the average of 16 disassembled models from 1999 to 2011 |
| Smartphone
finished product |
0.00189 g for one smartphone of 135 g, the average of 12 disassembled models from 2004 to 2015 |
Quantities, not harm: how much of the material the product’s chain requires. What that carries is not shown.
