The copper grades into a zone of 0.4 to 0.2 Cu within the biotitealtered zone at depth. Two discrete molybdenum ore shells are contained within the copper ore shell and are located proximal to the granodiorite stocks. The highest abundance of molybdenite is inward toward the stock and is zoned outward to lower grades.

CopperMolybdenum ores

CopperMolybdenum ores

Copper-Molybdenum ores. Molybdenite MoS2 is the predominant economic molybdenum mineral. While naturally very hydrophobic and can effectively be floated with just frother, addition of a hydrocarbon oil extender enhances its recovery. Making very pure moly concentrate grades is necessary for lubricant and oil additive applications so the challenge is primarily to effectively remove essentially all the

Bioleaching of molybdenum from lowgrade copper ore

Dec 01, 1999 Bioleaching of molybdenum from low-grade copper ores has been performed using the bacterium Thiobacillus ferrooxidans. The microorganism was isolated from the mine soil and adapted to molybdenum in a series of batch cultures. The effect of temperature, pH and culture media composition on the extent of bioleaching has been investigated.
