A 50 kg sample of tailings from Flin Flon was received in August 2023 and subsequent laboratory scale ‘proof-of-concept’ testwork was undertaken, including flotation, thermal decomposition of pyrite, and leaching of kiln calcine.
The overall results successfully achieved greater than 90% conversion of the pyrite into pyrrhotite and elemental sulphur.
These results will be used to design an overall flowsheet for the treatment of the tailings as part of the final test work. If the final test work results meet expectations, then further discussions concerning the next stages of technical cooperation will be held.
Future collaboration may include larger-scale test work in parallel with potential commercial negotiations.
