RE: RE: RE: RE: RE: Davis Tube Companies need to guarantee a minimum concentrate percentage for the life of the offtake deal. Different parts of the pits have different compositions, it's safer to guarantee a product you can definitely deliver.

Kami has relatively high silica and manganese, but very low sulfur and phosphorus, and a very high Davis Tube Weight Recovery. All of these technical factors help determine the best final product.

I'll try to look up the crude ore to concentrate ratio but I'm not sure it's public info. Where is this information available for Labmag and Kemag? I still hold to my original point, until there's convincing evidence to the contrary, why should I prefer an ore body with 29% iron and a 26% DTWR, over an ore body with 30% iron and a 37% DTWR?
