The treatment of copper–gold ores by ammonium
2002-10-1 · The process patented by Kerley was carried out in a plant in Mexico, but the scale-up from laboratory to plant-size failed. Perez and Galaviz (1987) describe the modifications required to make plant operation feasible. The most important process adjustment was the pH value, which should be maintained at a minimum level of pH 9.5, instead of 7.5 as suggested by Kerley (1981).

Gold in porphyry copper deposits: its abundance and fate ...
2002-10-1 · Gold abundances in porphyry copper deposits vary greatly, complicating efforts to define gold-rich porphyry copper deposits. The original definition was based on the Au/Mo ratios of porphyry copper deposits with no reference to their copper content , and resulted in the suggestion that gold-rich deposits were found largely in island arc regions (Kesler, 1973).
