Placer mining around Idaho Springs continued from 1859 to 1913, with the majority of gold recovered in the first three to four years after discovery. Crude arrastras were built as early lodemining work was attempted. In 1861, a 20stamp mill was built to process ore from the Whale, Lincoln, and other lode mines in the area.

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 than that of placer gold ore.
