Cyanide – Waihi Gold

2021-11-12 · The first cyanidation plant in the world was established close to Waihi, at the Crown Mine at Karangahake, in 1889. By 1892 there were six cyanide plants on the Ohinemuri Goldfield, plus others at Thames and Coromandel. The process was a great success, as the recovery of gold improved from 40-50% to 85-95%.

Factors influencing the rate of gold cyanide leaching and ...

2011-5-1 · But operating the plant at higher gold loadings slows the rate of adsorption of gold cyanide onto carbon and increases the gold losses in the barrens solution. This can be seen by comparing the profiles in Runs 2, 8 and 9, where the up-grading ratio was varied from 610 to 1000 to 1420, resulting in an increase in soluble gold losses from 0.001 ...
