How Gold Is Mined | Gold Mining Process | World Gold

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well

The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called

Weathered primary deposits are important to the gold industry because they are usually easier and cheaper to mine and the gold is easier to recover. Examples of primary deposits include those mined at Kalgoorlie in the Super Pit, Granny Smith, St Ives, Norseman and Mount Magnet (WA), Gympie and Ravenswood (Qld), Callie (NT), Stawell (Vic
