  • Gold Extraction Process Know How Gold Is Mined

    If surveyed correctly, a good gold mine would yield close to 6.5 g of gold for every 1000 kg of ore. Think about that. Gold ore is not pure, but instead intertwined with other metals like silver. In the mill, the large chunks of ore are crushed and broken down until it is a powdery sand-like mixture of gold
