Global battery demand and Australian lithium: processing shift for mine engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Surging global demand for lithium-ion batteries for electric vehicles and grid storage is pushing Australia to move beyond spodumene concentrate exports into domestic refining and cathode‑grade chemical production. Industry proposals centre on converting hard‑rock feed into battery‑grade lithium hydroxide and carbonate in Western Australia, leveraging existing Tier‑1 deposits and port infrastructure but facing high energy costs, skills shortages and permitting timelines. For miners and process engineers, the shift implies greater focus on impurity control, reagent optimisation and integration of hydrometallurgical circuits with upstream mine planning.
Technical Brief
- Several projects target modular hydrometallurgical trains, allowing staged ramp-up and debottlenecking of leach–purification circuits.
- Process design work is heavily focused on sulphate, sodium and magnesium removal to meet cathode-spec impurity limits.
- Tailings strategies are shifting from conventional wet storage to filtered residues to reduce freshwater demand and footprint.
Our Take
The related EV materials piece showing $15.8 billion spent on lithium and other battery metals in 2025 signals that Australian lithium projects now compete in a value chain where downstream chemicals (e.g. lithium hydroxide) capture a growing share of revenue versus raw spodumene exports.
Within our 105 lithium-tagged mining items, Australia consistently appears as a raw material hub rather than a processing centre, so any move into local value-add would mark a strategic shift from price‑taking concentrate supply towards more resilient, contract-backed chemical output.
For Australian lithium developers, the rising spend by cell and EV makers such as CATL, BYD and Tesla in the related article implies stronger leverage to negotiate offtakes that support domestic refining or conversion capacity, rather than continuing to ship unprocessed ore offshore.
