Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
ROM ore will not be economically viable for any of these deposits and it will not be possible to selectively mine zinc oxide ore with low acid consumption. Other similarities between the deposits include the presence of goethite as the dominant iron-rich gangue mineral. Zinc .
