Where the material actually goes
A flow map of the rare-earth magnet chain, drawn only from relationships that appear in a public document. Ribbon width is volume where a volume is published. Everything else is a dashed connector, because the relationship is documented even where the quantity is not.
Every flow, with its evidence
A contracted ceiling is not a rate. A delivered shipment is not an annual figure. A historical flow has stopped. Each is labeled as what it is.

Known gaps in this view
How the widths were derived
Two conversion factors do all the work in the NdPr view, and both are stated so they can be argued with. The Dy + Tb view uses no conversion factor at all: every sized flow there is a project's own published Dy and Tb figure, or arithmetic on one. The samarium view has no sized flow to convert.

Why there is no mixed-oxide conversion
The share of NdPr, or of dysprosium and terbium, in total rare earth oxide is a property of the deposit, not of the chain, and it ranges too widely for a single factor to mean anything. Browns Range xenotime is about 10 percent Dy + Tb by TREO; a large light-dominant deposit is a fraction of one percent. Where a project publishes its own split it is used. Where it does not, the flow stays unsized.
Why the views cannot be compared by width
Each view has its own currency and its own scale. A ribbon of a given width in the NdPr view carries a different tonnage from the same width in the Dy + Tb view, and a different element. The same goes for the samarium view. Compare within a view, never across.
