वास्तव में क्या चल रहा है
New Caledonia sits on one of the largest nickel resources on Earth and has smelted it locally for over a century. Its ore is the saprolite kind — good for metal, poor for batteries — so it goes into stainless steel rather than into cells. The economics turn almost entirely on the price of power on a small island.

Scraping the hillside
Laterite sits at the surface, so it is stripped with excavators rather than blasted. The soft, deeply weathered ore needs almost no drilling.
यहाँ क्यों: Millions of years of tropical rain on ultramafic rock made this deposit. It cannot be made anywhere the climate and the bedrock do not agree.

Drying and screening
Laterite arrives wet — often a third water by weight. It is dried and screened before it can be fed to a furnace.
शेष का क्या हुआ: 300 tonnes of that shipment was water. This is why laterite is almost never exported raw over long distances — you would be paying freight on rain.
यहाँ क्यों: Drying has to happen before shipping or smelting, and the cheapest place to do it is at the mine.

An electric furnace on an island
Calcined in a rotary kiln, then smelted in an electric arc furnace to ferronickel — an iron-nickel alloy that goes straight into stainless steel.
शेष का क्या हुआ: Almost everything else is slag. The nickel was never more than about 2% of what came out of the ground.
यहाँ क्यों: Smelting at home keeps the value and the jobs on the island. It also means every tonne of metal carries the cost of island power, which is the industry's permanent problem here.

To a stainless mill
Ferronickel is shipped as ingot or shot directly to stainless steel producers.
यहाँ क्यों: Ferronickel has exactly one customer: the stainless steel industry. It cannot be redirected to batteries.

Stainless steel
Melted with chromium and iron into austenitic stainless — sinks, cutlery, chemical plant, architectural cladding.
यहाँ क्यों: Two-thirds of all nickel still goes into stainless steel. The battery story is the newer and smaller half of the market.
