Testing upgraded 9–12% antimony feed material to an 89% product and then to 93%, while higher-grade concentrates yielded products grading 91–96% antimony.
What was announced
Locksley Resources reported breakthrough antimony-recovery results from its collaboration with Rice University.
According to the company, raw ore grading approximately 9% to 12% antimony was upgraded to an 89% antimony product and then further refined to 93%. Tests on concentrates grading approximately 65% to 70% antimony produced upgraded material grading between 91% and 96% antimony.
The program also produced antimony oxide and metallic antimony through electrodeposition, supporting Locksley's downstream-processing strategy for its U.S. antimony assets.
