Pachuca Tank

Pachuca tanks are used for a wide variety of leaching and mixing operations in the minerals industry. Previously, an equation was derived to predict the circulation in a Pachuca tank with full height draft tube risers. This analysis was subsequently verified with data from a large bore air-water flow loop used. However, the equation was based on …
