Molybdenum: mining and processing-Metalpedia

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.
