Mining History and Geology of the California Gold Rush
At least eight of the mines boasted total production in excess of 1,000,000 ounces Overall, hardrock mining accounted for about 60% of the gold produced in the Mother Lode and Sierra Foothills The most serious problem of mining the gold veins themselves was that quartz, the host ore, was an extremely hard What remained (hopefully) was raw gold, ready for the smelting process Smelting is the process of further refining the gold and melting it into bullion for sale and transportation Many gold mining towns were targeted by ‘bad men’ and would hold up the stage coaches hauling the gold ingotsBodie, California Hard Rock MiningOther articles where Sluicing is discussed: hydraulic mining: moving the slurry is called sluicing Educing is the process of introducing the slurry into an enclosed circuit In the hydraulic mining of gold the rebounding stream of water and mineral fragments is directed into sluices in which the gold settles behind baffles but the lighter waste matter is washedSluicing mining Britannica
