The first cyanidation plant in the world was established close to Waihi at the Crown Mine at Karangahake in By 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 The slurry that remains after this process has a very fine particle size Typically 80 of the ore particles are less than 70 microns in size about the same consistency as fine beach sand Such a fine particle size is required for gold liberation the size required for the cyanide to be able to ‘see’ the gold in the leaching process
