Innovations: How Hydrometallurgy and the SX/EW Process
The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a largescale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.

Cyanide Leaching Chemistry & Gold Cyanidation
Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.
