rotary concentrate


Molybdenum Processing - IMOA

Large rotary rakes move the molybdenite concentrate to promote the chemical reaction. Desulfurisation systems such as sulfuric acid plants or lime scrubbers remove sulfur dioxide from the effluent roaster gases. The resulting roasted molybdenite concentrate typically contains a minimum of 57% molybdenum, and less than 0.1% sulfur.
