GreenIron has a process to address a global market and efforts to lower the GHG output of metal production from Q3 2023. The outputs of the GreenIron process are valuable commodities extracted from magnetite, hematite, other metal oxides, minerals, waste, and residual products from the steel, mining, foundry, and manufacturing industries. The process is completely CO2 free, the only emissions from the process are water and metals. The solution can make a difference in the industry today as it works in batches, which enables modular and scalable operations close to the sources and our customers.
