Molybdenum Ores Article about Molybdenum Ores

Molybdenum is extracted as a by-product from other ores where its content is 0.005 percent or more. Molybdenum ores form under endogenous and exogenous conditions. Endogenous ores are related to skarn, greisen, and hydrothermal deposits. The major ore mineral in these deposits is molybdenite (MoS 2), which contains 60 percent molybdenum. Copper and tungsten—and, to a lesser extent, bismuth,

Molybdenum mines are classified into three groups according to the minerals contained in the ore body and their quality: •Primary mines, where the extraction of molybdenite is the sole aim. •By-product mines, where the extraction of copper-bearing ores is the primary aim, and molybdenite extraction provides additional economic value.
