  • How Gold Is Mined

    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.

  • How gold is made

    Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore Mining 1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks Gold is obtained from lode deposits by drilling, blasting, or.

  • The Mining Process

    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.
