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 the …
dence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropri-ate for ores that deplete cyanide and oxygen since this …
The leaching process. Leaching is the liberation of metals from ores by chemical dissolution, and it forms the basis of most hydrometallurgical extraction processes. The goal is to get the maximum amount of metal dissolved. It is an established and relatively successful method of metal extraction, especially when treating high grade ores.
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., …
