The leaching tests of gold ore in the copper-citrate-thiosulfate solutions are performed under various copper concentrations, and the results are shown in Fig. 9. As can be seen in Fig. 9 (a), an increase in leaching rate and extraction percentage of gold is observed during the first one hour of leaching process when copper concentration ...

The use of ammonia to reduce the consumption of cyanide during the leaching of gold from copper-bearing ores was patented in 1902 by Hunt (1902), during the first period of intense R&D activity in gold metallurgy that followed the invention of the cyanide process by J.S. MacArthur and the Forrest brothers in the late 1880s. The …
