Introduction to Gold and Silver Leaching The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in …
2.1. Overview and Industrial Applications. Leaching is defined as "the treatment of complex substances, like a mineral, with a specific solvent, able to separate its soluble parts from the insoluble ones" [].The process is used for the production of a concentrated solution of valuable solid material or to remove an insoluble solid from a …

The goals for agitator design in mineral processing must include maximising the tank's campaign online time. In other words, agitation reliability and therefore reduced frequency of maintenance is sought, whilst also achieving the most …
To start with, mineral thickener works on the principle of Gravity sedimentation and the most common construction of a thickener would be iron or steel. The continuous thickener consists of a cylindrical tank. Pulp is fed into the center of the tank via a feed well placed up to 1 m below the surface of the suspension.
