Massive trucks carry the ore to a crusher that breaks the rock into pieces less than 10 inches in diameter. The crushed ore then travels five miles by conveyer belt to the concentrator. There, we mix the ore with an aqueous solution and grind it into a fine powder. We then mix the ore powder with water, chemicals and air in flotation cells.

Molybdenum | Mo - PubChem
Molybdenum is a chemical element with the symbol Mo. Pure molybdenum exists as a dark-gray or black powder with a metallic luster or as a silvery-white mass. It does not occur naturally in the pure metallic form. It is principally found as oxide or sulfide compounds. Therefore, almost all exposure is to a molybdenum compound rather than the actual metal alone.
