Mining Process The easiest way to mine for gold was called panning a miner would scope up some of the sand from the river bend and swirl it around gold being one of the heaviest materials would sink to the bottom Once the gold sunk to the bottom it was easy for the miner to identify it as gold and they would pull it out of the mixture
