Oh no terryl I've been watching this thread for quite some time.
BTW does anyone know how many tonnes of ore it takes to make one tonne of usable steel. I imagine there must be some waste after processing.
How much does a standard piece of cement slab reinforcement weigh, if there is such a thing as standard, or a 10 meter steel girder weigh?
Just interested and trying to get some perspective and a handle what does 400 tonnes of ore actually means.
Cheers
