Indonesia refused to stay the low-value dirt seller. Two structural levers rewired the whole chain: the 2009 Mining Law that swapped foreign concession contracts for state-controlled permits, and the 2020 full export ban that dragged every smelter onshore. Chinese capital answered with the RKEF cost revolution and, later, HPAL wet-process plants to monetise the discarded low-grade limonite. The reward phase is over: the 2025–26 RKAB quota shock and falling grades now define a squeeze where new entrants fight over a shrinking, better-policed resource.
2009 — Law No.4: CoW → IUP, 5-yr export ban clock starts.
2013 — Tsingshan builds IMIP, mine-to-stainless in one park.
2020 — Total ban; NPI output overtakes China.
2026 — RKAB slashed 30%; Weda Bay runs dry by May.
High-grade saprolite is burning faster than it forms. Once the curve pierces the 1.70% RKEF floor, pyrometallurgy loses cheap feed and the resource-life debate turns urgent.
A 2,065-permit purge and multi-agency friction thinned the field. Fewer than 10 mines carry JORC-standard reports — the rest was fake-report land-grabbing, leaving true reserves a genuine mystery.
Pomalaa opens the field in the 1940s, mining 2.5%+ ore for Japan. ANTAM forms in 1968 (65,664 ha, 2nd-largest group), later shifting to East Halmahera as Pomalaa depletes. Canada's INCO signs a 30-year concession, builds Sorowako's first line (1973) backed by 365 MW of hydropower — becoming the largest owner at 118,017 ha.
China's stainless boom triggers barbaric procurement — Indonesia becomes ~55% of China's ore imports via the improved RKEF cost revolution. The watershed 2009 Mining Law converts CoW to IUP and arms a 2014 export ban. Tsingshan quietly buys 47,000 ha (2009) and builds IMIP (2013) — integrating mine to stainless steel.
From 1 Jan 2020 no grade may leave. Smelters relocate wholesale (Delong, Jinchuan, Lygend, Huayou, GEM); NPI output overtakes China, with Chinese-controlled firms at ~93% of exports. As batteries surge, HPAL monetises sub-1.7% limonite once dumped as overburden, producing battery-grade MHP.
Now >60% of world supply, Indonesia pivots to control-volume-lift-price. The Feb-2026 RKAB cuts the quota from 379 to ~265 Mt (-30%); Weda Bay is gutted -71% and halts by May. With grades sliding and <10 JORC-grade mines, capping second-class nickel becomes unavoidable.
Relative concentration of nickel mine-and-smelter activity by province.
| Location | Province | Operator | Scale / note | Role |
|---|---|---|---|---|
| Sorowako | South Sulawesi | PT Vale (ex-INCO) | 118,017 ha · 104 Mt · 365 MW | Largest owner |
| Weda Bay | North Maluku | Tsingshan 57% / Eramet 43% | 42→12 Mt quota (-71%) | Biggest single mine |
| Morowali (IMIP) | Central Sulawesi | Tsingshan | 47,000 ha · integrated 2013 | Mine → steel park |
| Pomalaa | Southeast Sulawesi | ANTAM | Since 1940s · 2.5%+ historic | Origin field |
| East Halmahera | North Maluku | ANTAM | 65,664 ha (group) | New frontier |
The 30% national cut lands unevenly: the world's biggest single mine absorbs a 71% cut and burns through its year by May — a textbook control-volume, lift-price move.
Vale's 118k-hectare block dwarfs the field and is hydro-powered. Tsingshan's footprint is smaller but vertically integrated — land size ≠ value; integration and grade decide margin.
Below the red line, RKEF is uneconomic and only HPAL unlocks value. The mass of tonnage is drifting downward — the industry's centre of gravity is crossing into wet-process territory.
Two-way dependence: China leans on Indonesian units, Indonesia leans on Chinese capital and process IP. That mutual lock is exactly what makes each quota decision a market-moving event.
30-yr concession from 1968; Sorowako line 1973. 118,017 ha, 104 Mt reserves, 365 MW hydro. The largest, cleanest resource — the benchmark asset.
Formed 1968 by merging state miners. 2nd-largest group at 65,664 ha, migrating from depleting Pomalaa toward East Halmahera — the national frontier vehicle.
Bought 47,000 ha in 2009, built IMIP (2013) and holds 57% of Weda Bay via Strand Minerals. From ore to stainless in one park — the integration blueprint.
A Sino-French joint control structure sits on the single most systemically important nickel asset on earth — which is why its -71% quota cut reverberates globally.
| RKEF | HPAL | |
|---|---|---|
| Feed grade | Saprolite ≥1.7% | Limonite <1.7% |
| Product | NPI → stainless | MHP → battery |
| China edge | Low-cost furnace revolution | Lygend·Huayou·GEM scale |
| Exposure | Grade decline | Battery demand |
RKEF built the stainless empire but is now squeezed by falling grades; HPAL is the escape hatch, converting yesterday's waste rock into the battery chain's core input.
The total ban forced capital onshore. Chinese-controlled firms — Delong, Jinchuan, Lygend, Huayou, GEM — rebuilt their smelters inside Indonesia, and by 2020 Chinese-controlled output supplied ~93% of exported NPI. What began as barbaric procurement of raw dirt ended as ownership of the world's nickel refining backbone.
The crisis is not one shock but six reinforcing bones. Policy and resource are the two you cannot arbitrage: quotas set the ceiling, grade sets the floor, and both point the same way — less tonnage, higher realised value, tighter control. New entrants are buying into a market where the reward phase has already been harvested.
1 — Next RKAB revision & any Weda Bay restart terms.
2 — Saprolite grade trajectory vs the 1.7% floor.
3 — HPAL/MHP capacity absorbing displaced limonite.
4 — JORC-report reconciliation of true reserves.
