It is a mineral. Further, the ore coming out of the ground contains the mineral wolframite amongst others. If it is coming out of the ground at a loss ( not making money ), it is not an ore. It is then only a collection of minerals. So, you have mineral deposits and orebodies. The distinction is a very important technical one. To learn more see Economic Mineral Deposits by Alan M. Bateman, of Yale University, John Wiley and Sons, 1950. Regards, John Archibald Mining Engineer Wolframite is not an ore. It is a mineral.
