Pick a material, a stage and a country, and say by how much its output falls. The tool shows how much of world output goes missing and what every other producer's share of the rest would be.
If mining output of cobalt in Democratic Republic of the Congo fell by 100 %, 73.1 % of world output would be missing.
This is arithmetic on one source table, not a forecast. It leaves out prices, stocks, substitution, new mines and how fast anyone could react.

Concentration of what is left (HHIHerfindahl–Hirschman indexA measure of concentration: the sum of the squared percentage shares of all countries. 10,000 means one country produces everything; below 1,500 is usually called unconcentrated.)

By value, from the trade table (2024). Only the largest flows of each material are in the atlas, so the list is not complete, and trade codes do not match production stages exactly.
HHI is the sum of squared country shares (10,000 = one country). Where the table leaves part of world output unattributed, it is a lower bound.
2.9 % of world output in this table is not attributed to a country and stays outside the calculation.
