Read Moreoct 04, 2019 the economically viable concentration of a mineral depends largely on its market price. gold ore can be viable at concentrations as low as 0.0001 percent, while copper becomes uneconomic below 0.5 percent. To reach these deposits underground, miners tunnel, dig open pits or scrape through the earths surface.
