The Mining Process Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

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...
