    My theory is that if some economical pre-treatment in a heap leach situation, could nullify the effects of the iron coating, chemically, then the pyritic ore could be effectively and economically leached with cyanide in the heap leach.

The gold extraction from the free milling ore sample was almost complete over 24 h of cyanide leaching while the addition of activated carbon (1% w/w) severely suppressed the extraction of gold (13.3%) into solution ...
