Amino acids key to new gold leaching process

In normal gold leaching you would leach with cyanide and then absorb the gold cyanide on to a carbonate leach carbon-in-pulp. He also recommends it for future in-situ heap leach extraction projects, a process that is expected to make mining low-grade deposits in remote locations more viable.

California Gold Rush - MJC Geology

Open Pit Mining and Cyanide Heap Leaching: Following the shutdown of most mining operations due to World War II, gold production reached a historic low in California. When the war ended, attempts were made to reopen several of the mines, but higher prices and flooding in the mines themselves doomed the efforts to failure.

The results showed that it was possible to selectively leach zinc from the ores by heap leaching. The zinc concentration of the leach liquor in the first leaching–extraction circuit was 32.57 g/L, and in the 16th cycle the zinc concentration was 8.27 g/L after the solvent extraction. The leach liquor was subjected to solvent extraction
