TMG US ANTIMONY DOWNSTREAM PROCESSING
ADVANCES WITH METSO AUSMELT TECHNOLOGY
HIGHLIGHTS
• Metso to deliver a Conceptual Study for processing antimony sulphide concentrate from Trigg’s
Antimony Canyon Project using Metso’s proprietary Ausmelt TSL smelting technology.
• The study will assess a smelter flow sheet concept aligned to produce 3,000–5,000 tonnes per
annum of 99.65% purity antimony ingot. The technology will allow future expansion.
• Two-stage furnace configuration under evaluation:
▪ Furnace 1: Converts sulphide concentrate to high-grade antimony oxide fume.
▪ Furnace 2: Treats oxide fume to produce crude antimony bullion for refining.
• Ausmelt TSL enables precise control of operating conditions, high metal recoveries, and energy
efficiency through submerged lance operation.
• The technology offers a low-emission, low-energy-intensity smelting solution that supports
Trigg’s commitment to environmentally friendly processing.
• Proven technology already deployed in 50+ global non-ferrous smelters; pilot-tested with
antimony concentrate from both Australia and China.
• The study supports Trigg’s strategy to develop a Western, vertically integrated antimony supply
chain.
