Gold cyanidation

Lead nitrate can improve gold leaching speed and quantity recovered, particularly in processing partially oxidized ores. Effect of dissolved oxygen. Oxygen is one of the reagents consumed during cyanidation, and a deficiency in dissolved oxygen slows leaching rate. Air or pure oxygen gas can be purged through the pulp to maximize the dissolved oxygen concentration.
