As expansion programs at South American brine operations slow down, the bulk of new lithium capacity is coming from hard rock mines.
While demand growth continues to accelerate the supply response has been dramatic. Last year saw four new spodumene operations enter the market and while concentrate (6% free on board Australia) traded either side of $900 a tonne for most of 2018, prices fell sharply in January.
According to industry tracker Benchmark Minerals combined output at these operations last year totalled over 175,000 tonnes and ramp up is continuing.
Apart from the new mines, Talison-Albemarle's Greenbushes spodumene mine, the world's largest, is doubling capacity and in January earthworks began on a massive new plant fed by the mine.
Any further decreases are expected to be marginal with many producers already operating at close to cost
Spodumene producers “experienced more pressure as 2018 contracts expired, ushering in a difficult period of negotiation for suppliers, as Chinese converters sought to receive significant discounts due to increased supply” says Benchmark:
While generally higher on the cost curve than brine operations, spodumene concentrate is converted into battery-grade lithium hydroxide which trades at around $16,000 per tonne ex-works in China, down from $20,000 six months ago.
Pumping and evaporating brine solution produces lithium carbonate which sometimes requires further refining or conversion to feed into the battery supply chain. Battery-grade lithium carbonate in China has halved in value over the past year and is now exchanging hands for under $12,000 a tonne.
At least the worst may be over for chemical prices says Benchmark:
