Global Rare Earth Refineries: The Chokepoint After the Mine

A text-based map of where rare-earth elements (REE) are actually SEPARATED into usable materials — not where the ore comes out of the ground. Sourced entirely from /n/wiki/Rare-earth element, /n/wiki/Mountain Pass rare earth mine, and /n/wiki/Lynas.

The load-bearing fact

REEs are not scarce. Cerium is the 25th most abundant element in the Earth's crust — more abundant than copper. The article states this directly: "rare-earth" is a misnomer. What is genuinely scarce is the industrial capacity to SEPARATE seventeen chemically near-identical elements out of the ore they come mixed in — a step requiring ion exchange, fractional crystallization, or liquid-liquid extraction, developed only in the late 1950s-60s and still expensive, toxic, and slow to build anywhere new.

The article gives two different numbers for two different stages of the same supply chain, and the gap between them IS the map:

China's share of global MINING: ~50-55% China's share of global REFINING: ~85-90% ("almost 90% of processing")

Mining is comparatively distributed. Refining is a near-monopoly. This piece maps the second number, not the first — the chokepoint is downstream of where the rock is dug up.

Legend

Named sites, by role

Mine-only, ore shipped elsewhere or not separated at all (per source):

ore is shipped out for separation, not processed on site

The one deliberate non-China refinery:

Built specifically to separate the ore Lynas mines at Mount Weld, in a different country entirely. The source calls it directly "the largest rare earth production facility outside of China." Its existence is a named exception to the general pattern, not an accident: Lynas chose to split mine and refinery across two countries by design, to break the China separation monopoly for its own ore. 2011 saw local protests over radioactive waste at the plant; construction was reviewed by an IAEA panel, cleared, and resumed.

Partial / rebuilding (US):

rare-earth mining AND processing facility in the US, supplied 15.8% of world REE production in 2020. Light-REE separation restarted in

  1. Heavy-REE separation is funded by the US Department of

Defense specifically to reduce supply-chain dependence on China, but per source is still under reconstruction — marked [P], not [R], because it does not yet match China's full separation chain.

China — mine and refinery co-located, the actual chokepoint:

ore deposit, and a major refining center in the same location.

the world's rare-earth supply is refined." Also the site of documented major environmental damage (thorium/radioactive tailings; Jiangxi province cleanup estimated at $5.5 billion by China's own Ministry of Industry and Information Technology).

source of HEAVY rare earths (dysprosium, terbium). Per a 2025 Benchmark Mineral Intelligence analysis cited in the source, the West will still depend on China for ~91% of heavy-REE needs by 2030 — down only modestly from ~99% in 2024.

The argument the map is making

Three structurally distinct roles, not one undifferentiated "rare earth industry":

  1. Digging REE ore out of the ground is geographically widespread —

the source names deposits across five continents.

  1. Separating that ore into usable individual elements is not. Only

one deliberate exception exists outside China (Kuantan, built by design across a border from its own mine), and only one active rebuilding effort exists in the US (Mountain Pass, still partial, backed by defense funding specifically because the gap matters strategically).

  1. China alone holds sites where mining and refining are CO-LOCATED

at scale (Bayan Obo, Baotou), plus a second, distinct near-monopoly specific to heavy rare earths (the southern ionic-clay deposits) — this second monopoly is even harder to break than the first, per the source's own 2030 projection.

What this map is not

It is not a mining-location map (a much more even scatter — the source names deposits across Africa, South America, Europe, Oceania, and Asia). It is not the same argument as the already-delivered battery-gigafactory piece, which concerned finished-cell manufacturing SCALE and vertical integration; this piece concerns a specific chemistry-and-capital chokepoint (separation), the step between "ore in the ground" (not scarce) and "usable REE oxide" (the actual bottleneck).
