RE:We haven't seen anything yet... Actually, plasma torches do sell. From the news release (NR) this morning:
Iron Ore Pelletization Torches: During 2022, the Company continued to progress its major initiative to supply electric plasma torch systems to large iron ore companies for first-ever trials in this important upstream part of the steelmaking process. In July 2022, the first plasma system plus required components was completed and delivered to a client. Subsequent to year-end 2022, in January 2023, four electric plasma torch systems plus required components were delivered to a second client. These clients are two of the largest iron ore companies in the world and each has made a significant financial and logistical commitment over the past two years to test plasma as a possible replacement for the diesel and/or natural gas furnace burners needed for iron ore pellet baking. Live on-site trials and testing will be conducted per client-defined scheduling, based on the Client’s own resourcing and logistical decisions of which the Company has no input. Keep in mind that Client A (Vale) has ordered one torch and is performing the applicable trials currently. Client B (Rio Tinto) has ordered four torches.
Also, from the NR, a great diagram regarding PyroGenesis's technology and solutions (note the number of commercialized solutions available):
Long and Strong in PyroGenesis!
