Gossan is defined as being an iron-bearing capping over a sulfide deposit. It is formed by the oxidation and leaching of sulfide minerals, leaving hydrated iron oxides such as limonite and goethite, along with manganese oxides.
Tabling and jigging are two relatively inexpensive methods for recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many ores contain appreciable amounts of “metallic salts” that readily dissolve in one’s system water and continue to migrate right along with this water.
At the start of the 20th century, copper was king in Arizona, with one of every four workers employed in the mining trade. On the brink of a new millennium, however, the industry is no longer the cornerstone of the state's so-called "Five Cs" economy—copper, cattle, cotton, citrus and climate.
