Iron ore should contain about 30 percent iron if it is to be mined profitably. Gold ores containing as little as 0.044 ounce (1.25 grams) of gold per ton can be mined at a profit. Magnesium can be removed from sea water at a profit by special methods. Gold, though present in sea water, cannot yet be extracted profitably.

Smelters Colorado Miners Doing History Keeping the Past
The ore smelting business helped develop coal mining in Colorado. The smelters needed fuel for their blast furnaces. After cutting down the nearby forests for wood, the smelter owners began using coke. Coke is coal that is partly burned to remove impurities. The remaining coke burns much hotter than ordinary coal.
