Under the conditions on the Gogebic iron range, Michigan, where much of the capping carries 40 percent or more iron, a small amount of dilution does not seriously affect the grade of ore mined and the dilution from this source may offset tonnage of ore lost; the net result is therefore likely to be approximately 100 percent tonnage recovery, with a slight lowering of the total contained iron

In heapleaching, the ore is placed on openair pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered.

Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to remove this iron coating and then make the fine
