EFFECT OF PRESSURE ON GOLD CYANIDE LEACHING

SUSTAINABLE EXTRACTION AND PROCESSING OF RAW MATERIALS, 2021
Although the effect of high oxygen pressure on gold recoveries at elevated slurry temperatures was previously investigated, the sole effect of the pressure at ambient temperatures on cyanide leaching with the presence of nearly enough oxygen for the cyanide reactions to occur has not been found to be studied. This research work was carried out with the
