ما الذي يتنقّل فعلاً
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.

- Spodumene concentrate, 6% Li2O, from an LCT pegmatite
- حيث يبدأ
- Australia — Greenbushes, Western Australia — the highest-grade hard-rock lithium mine in the world
خطوة خطوة، وحدًّا حدًّا
Australia · Greenbushes, Western Australia بحوزة Talison Lithium (شركة التعدين)
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.
لماذا هنا: The pegmatite is here. Greenbushes was mined for tin for a century before anyone wanted the lithium.
Australia · Concentrator on site بحوزة Talison Lithium (شركة التعدين)
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.
ما الذي جرى للباقي: 880 tonnes to tailings. Concentrating on site is essential — shipping the waste rock across an ocean would be absurd.
لماذا هنا: You concentrate as close to the pit as possible, always. Freight is charged by the tonne.
China · Port Hedland or Bunbury to Chinese ports بحوزة Traders and converters (متداول)
Bulk carrier to China
Shipped as bulk concentrate. This is the step that made spodumene a spot-traded commodity with a visible price.
لماذا هنا: 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 بحوزة Converter (كيميائي)
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.
ما الذي جرى للباقي: 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.
لماذا هنا: Energy, acid, chemical engineering and a qualified customer next door.
South Korea · Cathode and cell plants بحوزة Cathode and cell manufacturers (الشركة المصنّعة)
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.
لماذا هنا: High-nickel cathode expertise sits in a small number of Korean, Japanese and Chinese firms.
United States · Wherever it is sold بحوزة The driver (المستخدم النهائي)
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.
لماذا هنا: Four countries, two oceans, and about four months from blast to battery.
هذا مثال تطبيقي. يتتبّع كمية ابتدائية محددة عبر معدلات عائد واسترداد نموذجية منشورة، مما يجعل النسب قابلة للتحقق؛ وهو ليس سجلاً لشحنة فعلية. وقد جُمعت وقائع المسار — الدول، والعمليات، وأسباب تعذّر معالجة المادة في مكان آخر — من تقارير متاحة للعموم.
