MINERAL EXPLORATION AND MINE DEVELOPMENT

2014-7-18 · Ore is the rock from which an element ultimately will be extracted. The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating mines—much less than 1% by weight for gold, more than 60% by weight for some iron-ore mines. Ore usually is transformed into concentrate at the mine site.
