This is a list of countries by gold production in 2018.. Until 2006 South Africa was the world's largest gold producer. In 2007 increasing production from other countries and declining production from South Africa meant that China became the largest producer, although no country has approached the scale of South Africa's period of peak production during the late 1960s and early 1970s.
Removing the gold bearing rock from the ground is just the first step. To isolate pure gold,panies useplex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel like material then enters rotating drums filled with

At Olympic Dam SA gold occurs and is mined with copper and uranium. Secondary deposits are no longer major sources of gold in Australia. Gold usually occurs in its metallic state, commonly associated with sulphide minerals such as pyrite, but it does not form a separate sulphide mineral itself.
The process begins when geologists take ore samples to determine the best placespanies 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, its mined with open pit mining techniques. Gold thats located farther below the surface is collected with underground mining
