Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated …

With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
