Selecting a Gold Recovery System
March 2001
Tabling and jigging are two relatively inexpensive methods of recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many gold ores contain appreciable amounts of “metallic gold salts,” some of which readily dissolve in the system water and continue to migrate right along with it.
