Concentration of Gold Ores a Key to Reducing

In artisanal gold mining, mercury is essentially used to concentrate the gold. It does this by bonding with the gold to form a heavy amalgam that is then easily separated from the other minerals. It follows therefore, that if mercury is used as a mechanism of

Gold Ore an overview ScienceDirect Topics

The Mother Lode District of California may be the most famous of a class of lode gold-ore deposits that are found in metamorphic terranes associated with accretionary plate tectonics. They have also been called greenstone-belt and mesothermal lode ores (Figure 1). The discovery in 1848 of placer gold at Sutter's Mill, downstream from this district, led to the California Gold Rush of 1849, one of the most
