RE:RE:RE:RE:RE:Rio Tinto Plasma Torch Follow-UpFrom memory the plant could easily be 1/4 mile X1/4 mile. That would include all ore processing facilities : ore crusher and grinding for concentrate production, gravity and magnetic separation for concentrate producton, and then the pellet plant more grinding, balling, and induration machines. That does not include ore storage shed, product load-out to unit trains or any of the actual mining operation or support buildings garages warehouses mine dry and administration.
From the RIO annual report for 2020 : 18 million tonnes of product of which as much as 10 could be pellets if everything was working. 2716 employees including the railroad and ore shipping (storage yards and ship loading ). Rumours have it that IOC made about 1 billion $ in net profit in 2020 and 2021 will be even better.
For better info go to the IOC web site. The Carol Lake project has been producing since the mid 60s and has proven and possible reserves for well beyond 2050.
