Trigg Minerals (ASX:TMG) has brought Finnish Metso, a global leader in minerals processing and metals refining technologies, on board to develop an “advanced, scalable” solution for processing antimony sulphide concentrates.

This content has been prepared as part of a partnership with Trigg Minerals Ltd and is intended for informational purposes only.
The industrial machinery producer boasts a smelting technology called Ausmelt Top Submerged Lance (TSL) that Trigg is eager to employ.
With TSL in hand, Trigg will be running a study to assess whether a smelter flowsheet concept can produce 3,000 to 5,000 tonnes of 99.65% pure antimony ingots a year; the goal, the company said today, is “expansion.”
“This proposal marks a critical step forward in our strategy to establish a reliable, Western processing pathway for antimony at our Antimony Canyon Project,” the company’s managing director, Andre Booyzen, said.
“Metso’s Auselt offers a proven, mature, modern, scalable platform [with] the potential to produce high-purity antimony with reduced environmental impact.”
One of Ausmelt TSL’s biggest selling points is its lower carbon footprint relative to conventional smelting methods, which is achieves through high thermal efficiency and oxygen-enriched combustion.
With that in mind, Trigg will begin a three-stage testing run this month.
The multi-stage pyrometallurgical flowsheet will begin with the smelting of antimony sulphide concentrates to generate high-grade antimony oxide fume.
Trigg and Metso will then treat that oxide fume to produce crude antimony metal before refining that new metal to assess the potential to produce refined antimony metal at that aforementioned 99.65% target purity.
All this would then, of course, be funnelled into use at Trigg’s Canyon project.
