    Hi,

    I had a question about how to roughly calculate the required tonnes of input ore to generate a tonne of concentrate.
    e.g. I have a magnetite resource at 18.6% Fe, the processing only gets 70% recovery and the output grade is 67%.
    so is it just
    67%/(18.6% x 0.7) = 5.15 tonnes?
