Molybdenum Mining - IMOA

Molybdenum is contained in various minerals, but only molybdenite (MoS 2) is suitable for the industrial production of marketable molybdenum products. Molybdenite can occur as the sole mineralization in an ore body, but is often associated with the sulphide minerals of other metals, notably copper. The Mo content of viable ore bodies ranges between 0.01 and 0.25%.
