GMC Chart, page-74

Its pointless taking any notice of a table where all the inputs are either out of date or not included. The price of FeSi is shown as US$1,035/tonne. Yeah right, that was back in 2016, its now closer to US$1600/tonne. So add another US$688 to your costs, so US$1251.64 + US$688 =.US1939.64. Only problem now is that the price of MC FeMn is under US$2000/tonne. Great profits eh!!!!!
What about electricity, the table works it out at US$0.09c/KWh, even if it is at that price now it won't be after the next election in 2019.
