flag Australian firm Locksley restarts U.S. antimony production using new clean tech, reducing reliance on China.

flag Locksley, an Australian mining company, is working to restart U.S. antimony production after a year-long export ban, using a new low-temperature hydrometallurgical process developed with Rice University. flag The DeepSolv technology, which uses deep eutectic solvents, aims to extract antimony more efficiently and cleanly than traditional smelting. flag Based at its Mojave project in California near the Mountain Pass rare earths mine, Locksley is advancing toward a pilot-scale demonstration, targeting high-grade stibnite concentrates of up to 50% with improved recovery rates. flag The project has gained support from U.S. policymakers and advisory firm GreenMet as part of broader efforts to reduce reliance on Chinese supply chains for critical minerals.
