The iron oxides in the ore were derived from the Negaunee Iron-Formation and were concentrated during the transgression marked by the onset of Goodrich deposition.Hard ore accounted for about 20 percent of high-grade ore production from the Marquette Range; about 67 million tons were produced.
Jan 01, 2016· 1. Introduction. Since the discovery of the supergiant Olympic Dam deposit in Australia in 1975, Iron Oxide Copper–Gold (IOCG) deposits have become the largest producer of uranium (Hitzman and Valenta, 2005, Skirrow, 2011), the third producer of copper (Sillitoe, 2012) and significant producer of gold (Kerrich et al., 2000, Frimmel, 2008, Porter, 2010).
The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from gold ore rather then actual Gold specimens.
