Hard-rock lithium is mined and floated like any other ore, then shipped as a concentrate to be cracked open with heat and acid. It is faster to start, faster to stop and faster to expand than a salar — which is why hard rock, not brine, supplied most of the growth of the last decade.
- Materialnya
- Lithium
- Varietasnya
- Spodumene concentrate, 6% Li2O, from an LCT pegmatite
- Titik awal
- Australia — Greenbushes, Western Australia — the highest-grade hard-rock lithium mine in the world
Langkah demi langkah, perbatasan demi perbatasan
Australia · Greenbushes, Western Australia dipegang oleh Talison Lithium (Penambang)
Drill, blast, load, haul
Conventional open-pit mining of a zoned pegmatite. The ore is unusually rich in lithium for hard rock, which is why this mine stays profitable through price crashes that shut others.
Mengapa di sini: The pegmatite is here. Greenbushes was mined for tin for a century before anyone wanted the lithium.
Australia · Concentrator on site dipegang oleh Talison Lithium (Penambang)
Crushing and floating to a concentrate
Crushed, ground, and separated by dense-media separation and flotation until the spodumene is concentrated to about 6% Li2O.
Apa yang terjadi pada sisanya: 880 tonnes to tailings. Concentrating on site is essential — shipping the waste rock across an ocean would be absurd.
Mengapa di sini: You concentrate as close to the pit as possible, always. Freight is charged by the tonne.
China · Port Hedland or Bunbury to Chinese ports dipegang oleh Traders and converters (Pedagang)
Bulk carrier to China
Shipped as bulk concentrate. This is the step that made spodumene a spot-traded commodity with a visible price.
Mengapa di sini: The converters are in China. Australia has built some conversion capacity, and found out how hard commissioning a lithium chemical plant to battery specification really is.
China · Sichuan or Jiangxi dipegang oleh Converter (Kimia)
Roasting at 1,050 °C, then acid
The concentrate is calcined to flip alpha-spodumene into the beta form, then digested in concentrated sulfuric acid and purified into lithium hydroxide or carbonate.
Apa yang terjadi pada sisanya: The sulfuric acid used here is largely a by-product of oil refining and metal smelting — the same sulfur that came off a heavy crude barrel elsewhere in this atlas.
Mengapa di sini: Energy, acid, chemical engineering and a qualified customer next door.
South Korea · Cathode and cell plants dipegang oleh Cathode and cell manufacturers (Produsen)
Cathode, cell, pack
Hydroxide is preferred over carbonate for high-nickel cathodes because it calcines at a lower temperature. It becomes cathode powder, then a coated electrode, then a sealed cell.
Mengapa di sini: High-nickel cathode expertise sits in a small number of Korean, Japanese and Chinese firms.
United States · Wherever it is sold dipegang oleh The driver (Pengguna akhir)
A long-range electric car
The same 8 kg of lithium as the Chilean route delivers — from 1,000 tonnes of rock instead of a million litres of brine.
Mengapa di sini: Four countries, two oceans, and about four months from blast to battery.
Ini adalah contoh terhitung. Contoh ini mengikuti kuantitas awal yang dinyatakan melalui hasil dan perolehan tipikal yang dipublikasikan, sehingga proporsinya dapat diperiksa; ini bukan catatan pengiriman tertentu. Fakta rute — negara mana saja, proses apa saja, dan mengapa material tersebut tidak dapat begitu saja ditangani di tempat lain — dikompilasi dari laporan publik.
