Byproduct of copper ore processing plant molybdenum. The molybdenum ore processing plant would produce 5,000 tons a year of molybdenum separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite .
Coproduct mines, where the commercial viability of the mine requires that both molybdenite and copperbearing minerals be recovered. If the ore lies close to the surface, open cast pit technology is employed. Here the overburden is excavated to reveal the ore .
