Gold Ore

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 …

How to Extract Gold From Seawater

Gold from seawater? Yes, it is possible and there is plenty there. With gold prices over $1000 an ounce, then the pressure is on to develop economical methods of extraction.
