Gold miners have to smelt their gold in order to remove impurities resulting in pure gold. Most large scale gold miners send their ore to smelters with large equipment for the smelting process. Small scale miners still can do their own smelting using specialized kilns. Many people confuse gold smelting with melting.

Mines can make money processing ore on a large scale, but we are talking about millions and millions of tons. Individually, the average chunk of ore has very little to no mineral value. Buying a 5 pound piece of ore on eBay is only going to be worth a dollar or two in the BEST CASE scenario, but most likely it is worth almost nothing.

Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.
