  • BACKGROUND NOTE ON CYANIDE IN GOLD MINING

    Cyanide use in mining Gold typically occurs at very low concentrations in ores – less than 10 g/ton The most used process for gold extraction is hydrometallurgical recovery (gold cyanidation), which involves a “leaching” step during which the gold is dissolved in an aqueous medium, followed by theThe gold aurocyanide complex in the aqueous phase is readily adsorbed onto the activated carbon By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0001 and 002 ppm with a value of 001–0005 ppm regarded as a practically achievable value for most wellThe process design of gold leaching and carboninpulpThe Dorr Leaching Agitator The Dorr agitator, in general use today, is a combination mechanical and air agitator designed for use in round, flat bottomed tanks as large as 50 ft in diameter and 25 ft in depth The pulp and coarse solids from the bottom of the tankGold Leaching Agitation Tanks
