IMOA facts and figures

The mined ore is crushed, ground, mixed with a liquid and aerated in a flotation process to separate the metallic minerals from the rock. The resulting concentrate contains between 85% and 92% industrially useable molybdenum disulfide (MoS 2).Roasting this in air at 500 to 650 176;C produces roasted molybdenite concentrate or RMC (Mo0 3), also known as technical Mo oxide or tech oxide.

Molybdenite

Molybdenite is an important ore of molybdenum, and is the most common source of the metal. While molybdenum is rare in the Earth's crust, molybdenite is relatively common and easy to process, and accounts for much of the metal's economic viability. Molybdenite is purified by froth flotation, and then oxidized to form soluble molybdate
