Spud pric: why I think it will rise (not discussed here yet?)2 Apr 2026 12:23
Interesting times:
Sulphur, prices have risen significantly.
China does not have enough sulphur imports 50%
40% comes from Middle East.
Sulfur prices have seen extreme volatility, recently reaching peaks of nearly 6,260 CNY/t (approx. $865 USD/t).
Consumption Penalty: Because lepidolite requires 3–4 times more sulfuric acid per tonne of lithium produced than SC6 spodumene, high sulfur prices act as a direct tax on low-grade refining.
Cost Gap: Processing lithium from lepidolite in China currently costs between 80,000–120,000 RMB/t, whereas spodumene refining remains closer to 60,000 RMB/t. Surging sulfur prices are pushing lepidolite costs toward the higher end of that range, making it a "marginal" or loss-making source for many.
Priority Shift: During sulfur shortages, the Chinese government typically prioritises agricultural fertilisers over industrial lithium refining.
Competition for SC6: This forced scarcity is driving a rush for high-grade spodumene from "safe" sources like Australia and Africa, causing spodumene prices to rise independently of the lithium salt market
