Ore processing – Waihi GoldOre processing consists of the following stages: crushing and grinding of the ore; addition of process water (generally decanted from the tailings pond) to form a slurry; addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution; addition of carbon to adsorb (attach) dissolved metals.Sulphide Gold Ore Treatment by Leaching and Flotation ProcessJan 11, 2018 . In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an oxidized ore. A neighboring mine may have a higher tailing loss but still make more money due to lower milling costs. For many years, after introduction of.
