Classification, Distribution and Uses of Ores and Ore Deposits

Other classes of ores comprise minerals that are used in their natural state without refinement or extraction of a specific element. Barite, a sulfate of the heavy element barium, is employed to increase the density of the fluids ("muds") used when drilling for oil. Uranium and coal are sources of energy.
