What this place is
Indonesia's rise to dominate world nickel came from banning ore exports and forcing processing onshore — Sorowako is the older, pre-ban model of an integrated mine and smelter.
Grade. Saprolite laterite ore suited to smelting into matte rather than leaching.
“Grade” is the percentage of the useful stuff in the rock. A copper mine at 0.5% grade throws away 199 tonnes of rock for every tonne of copper it sells. That single number decides whether an orebody is a mine or just an interesting piece of geology.
What comes out
Nickel
A silvery metal that resists rust, which is why it goes into stainless steel — and, more recently, into the cathodes…
Cobalt
A hard, bluish metal that keeps a battery's cathode stable so it does not overheat, and that holds its strength when…
A “by-product” is a metal recovered because it happens to be in the same rock, not because anyone went looking for it. Its supply therefore follows the primary metal’s economics, not its own.
