Gold Ore Tank leaching vs. Vat leaching
In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank.
Alternative Lixiviants to Cyanide for Leaching Gold Ores
Chlorine, bromine, and iodine are well-known lixiviants for leaching gold, as reviewed by Tran et al. (2001). Chlorination was applied extensively in the late 19th century before the introduction of the cyanidation process. Bromine/bromide for leaching gold from ores was reported as early as 1846.
