Gold Leaching Gold Leaching. Gold occurs in nature as the element (more commonly as an alloy of Au and Ag, or Au and Te, etc.). Ores may contain as little as 1-10 g Au/t (only 1-10 parts per million!). ... The leach solution should not be corrosive to plant equipment and materials. The leach solution should be as non-toxic as possible. Summary ...
