Molybdenum Ore Processing by Flotation

The “Sub-A” Unit Flotation Cell is one of the most important parts of the circuit, for it not only removes a major portion of the remaining molybdenum mineral as a high grade product, but may also be used to remove a greater tonnage of a middling product for later up-grading if the metallurgist may determine.

Molybdenum Flotation - Mineral Processing & Metallurgy

Molybdenum Flotation. A Molybdenum Flotation case study with about 6% of the molybdenum contained in the feed is present as an oxide form and about 90% of this is not recovered to the flotation concentrate. Recovery of molybdenum into the rougher concentrate varied between 90 to 95% at a concentrate grade of 2.5 to 3.7% molybdenum.

Copper-Molybdenum ores - Danafloat

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...

Moly Removal From Wastewater | Products Finishing

Sep 01, 2006 · While reverse osmosis can remove molybdate, it generates a reject stream of between 5–15 % of its flow, and this reject stream still has to be treated. For a “closed loop” option, ion exchange could be a feasible option. Strong base anion resins are capable of removing the molybdate ion.

Removal of Molybdenum from Waste Water

Recommended Bench Scale Tests for Molybdenum Removal. Test 1. Determine the amount of soluble and insoluble Molybdenum by filtering. Use a 10 micron filter for this test. Simple filtering may do the job. Test 2. Remove the high concentration by adsorption using a sodium bentonite clay to bring down an initial high concentration.

Molybdenum Processing -

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.

Molybdenum - Wikipedia

Copper, an impurity in molybdenite, is less soluble in ammonia. To completely remove it from the solution, it is precipitated with hydrogen sulfide. Ammonium molybdate converts to ammonium dimolybdate, which is isolated as a solid. Heating this solid gives molybdenum trioxide: (NH 4) 2 Mo 2 O 7 → 2 MoO 3 + 2 NH 3 + H 2 O

rougher flotation, at the same time effectively removing the floated calcite from the rougher concentrate [6]. In this study, we aimed to collect molybdenum and fluorite in separate phases and to increase flotation yield. Therefore, before the flotation, the sulfurization process was made in order

Introduction to Mineral Processing - Chevron Phillips Chemical

The froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers. This enriched material is now called the rougher concentrate or cleaner feed . The combined rougher-scavenger concentrate may be 5% Cu and 0.06% Mo (a concentration factor of 3 to 10 times is typical).

How can I decrease molybdenum in the rougher and scavenger ...
