Copper-Molybdenum ores

Copper-Molybdenum ores Molybdenite (MoS 2) 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

Copper–molybdenum ores flotation in sea water ...

01.11.2013  Laboratory rougher flotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH (pH 7–12). Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5. Frothers

HV-2 Copper Molybdenum Ore EVISA's Materials Database

The source material for HV-2, two lots of ore grade material and a molybdenum concentrate, was donated by Highland Valley Copper in Logan Lake, British Columbia in 1997. The ore grade materials were dried at 66°C for 24 hours and the concentrate was dried at 105°C for 4.5 hours. After crushing and sieving each component separately to a mesh size of less than 75 µm, the

Copper-Molybdenum ores - Danafloat

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. Further, because optimum moly flotation pH

FLOTATION PROCESSING OF COPPER-MOLYBDENUM ORE

Keywords: copper-molybdenum ore, flotation, dispergation, concentration, extraction INTRODUCTION As the deposits are depleted and the need arises to involve poor, finely disseminated ores in processing, it becomes necessary to improve the reagent modes of en-richment of copper ores, the use of additives and rea- gent compositions, the use of

Molybdenum Ore Processing by Flotation

05.05.2016  Molybdenum is found in small amounts in practically all low grade porphoritic copper ores. It is usually present as the sulphide, molybdenite, which is readily recovered in the copper flotation concentrate. Copper sulphide flotation concentrates may contain from 0.25 to 1.00% MoS2. When such ores are milled in large tonnages the amount of molybdenum

01.10.2017  A copper–molybdenum iso-flotability flotation process has been developed to efficiently improve the recovery of molybdenite from Duobaoshan porphyry Cu–Mo ores. The effects of flotation approach, type of collector, feed particle size distribution, rougher pH value and reagent dosage on the recovery of molybdenite were evaluated systematically.
