वास्तव में क्या चल रहा है
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.

चरण दर चरण, और सीमा दर सीमा
Australia · Greenbushes, Western Australia द्वारा धारित Talison Lithium (खनिक)
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.
यहाँ क्यों: The pegmatite is here. Greenbushes was mined for tin for a century before anyone wanted the lithium.
Australia · Concentrator on site द्वारा धारित Talison Lithium (खनिक)
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.
शेष का क्या हुआ: 880 tonnes to tailings. Concentrating on site is essential — shipping the waste rock across an ocean would be absurd.
यहाँ क्यों: You concentrate as close to the pit as possible, always. Freight is charged by the tonne.
China · Port Hedland or Bunbury to Chinese ports द्वारा धारित Traders and converters (व्यापारी)
Bulk carrier to China
Shipped as bulk concentrate. This is the step that made spodumene a spot-traded commodity with a visible price.
यहाँ क्यों: 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 द्वारा धारित Converter (रासायनिक)
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.
शेष का क्या हुआ: 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.
यहाँ क्यों: Energy, acid, chemical engineering and a qualified customer next door.
South Korea · Cathode and cell plants द्वारा धारित Cathode and cell manufacturers (निर्माता)
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.
यहाँ क्यों: High-nickel cathode expertise sits in a small number of Korean, Japanese and Chinese firms.
United States · Wherever it is sold द्वारा धारित The driver (अंतिम उपयोगकर्ता)
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.
यहाँ क्यों: Four countries, two oceans, and about four months from blast to battery.
यह एक कार्यसाधित उदाहरण है। यह एक घोषित आरंभिक मात्रा को प्रकाशित सामान्य उपज और पुनःप्राप्ति दरों के माध्यम से अनुसरण करता है, इसलिए अनुपात जाँचे जा सकते हैं; यह किसी विशिष्ट शिपमेंट का अभिलेख नहीं है। मार्ग संबंधी तथ्य — कौन-से देश, कौन-सी प्रक्रियाएँ, और क्यों सामग्री को कहीं और संभाला नहीं जा सकता — सार्वजनिक रिपोर्टिंग से संकलित हैं।
