Magnesium Prices See Volatility Amid Coal Cost Fluctuations, Demand Weakness Persist

Published: Sep 11, 2026 16:51 (GMT+8)
【SMM Magnesium Weekly Review】 This week, the supply structure of dolomite sources has diverged: high-quality local ore sources in Wutai remain persistently tight, and enterprises have procured from other provinces for replenishment, resulting in overall sufficient supply and stable prices. Driven by sharp fluctuations in coal prices, magnesium ingots in major production regions saw a trend of first rising then falling: at the start of the week, raw material hikes pushed magnesium prices to a peak, but downstream customers reduced purchases out of fear of high prices; coupled with the subsequent decline in coal prices, magnesium ingots gave back all their earlier gains. Foreign trade FOB quotations edged down slightly along with domestic prices, overseas orders fell short of expectations, the "Golden September and Silver October" demand failed to materialize, and traders showed strong wait-and-see sentiment. Downstream magnesium powder and magnesium alloy are under simultaneous pressure: magnesium powder fluctuates in line with magnesium ingots, processing fees are under pressure, and downstream players only maintain inelastic demand; magnesium alloy is in a situation of weak supply but even weaker demand, with die-casting plants seeing declining operating rates, rising inventories and weakening processing fees. On the whole, the magnesium industry chain this week is mainly disturbed by coal costs, with no substantial recovery in terminal demand and a lack of strong support across the industry, maintaining a weak oscillating pattern in the short term.

【SMM Magnesium Flash】On October 1st, Latrobe Magnesium released an updated project status, indicating that the installation progress of its Phase 1B demonstration plant in Victoria has reached 90%, marking a significant increase from 70% at the end of August. Overall commissioning is 25% complete, with successful dry test runs of the ball mill and briquetting machine. Key installation activities in the reduction furnace area have been completed, and vacuum testing is currently underway for 30 sets of distillation tanks and condenser components. The company maintains its target of producing the first batch of magnesium metal (purity >98%) by the end of 2026, and project expenditures are being controlled within the original budget of AUD 6.1 million. As the demonstration line gradually commences production, its low-carbon process route for extracting magnesium from lignite ash is expected to undergo industrial verification.
