The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke the limestone aiding slag separation from the molten iron.
The concentration of variable of interest (gold is very low while in iron ore iron is very high) The continuity (and orientation) of the geology and mineralisation (gold short and iron ore usually long) The cost of the sampling (blast holes you get for free RC drilling you must pay for).
A blast furnace is finely tuned requiring input ore of consistent grade not only in its iron content (typically up to about sixty percent iron) but also in its content of the major contaminants silica and alumina (each a few percent) and phosphorus (a fraction of one percent).
