Mining Techniques of the Sierra Nevada and Gold Country

Hydraulic mining was a potentially efficient method of getting gold out of the ground, but it was also the most environmentally destructive. The principle was very simple but devastating — water under pressure would be directed against a bank of gravel deposits and the hillside would wash away rapidly.get price

Gold Mining and Processing: Everything you Need to Know

The Basics of Gold Mining and ProcessingWhat Is Gold Used for?Where Is Gold Found?The Gold Mining ProcessPlacer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is...

OverviewHistoryStatisticsMethodsGold ore processingBusinessAdverse effectsSafety

It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old. A group of German and Georgian archaeologists claims the Sakdrisi site in southern Georgia, dating to the 3rd or 4th millennium BC, may be the world's oldest known gold mine. get price
