Molybdenum Ore Processing by Flotation

The usual flotation reagents are the xanthates and a selective frother such as Dowfroth 250 or one of the light alcohol type frothers. The flotation steps usually consist of roughing, scavenging, cleaning and recleaning to provide a high grade copper concentrate which contains the bulk of the contained molybdenite. All of these steps may be successfully accomplished in “Sub-A” Flotation Machines

Improving fine molybdenite flotation using a combination

01/03/2019 The flotation of molybdenum single mineral was conducted in an XFG hanging flotation cell. 2.0 g molybdenum mineral was mixed with 50 mL distilled water and agitated at 1780 rpm. NaOH solution was added to adjust the pH at about 6.5. Then, 40 mg/L collector (kerosene with or without PAH) was added and conditioned for 3 min, followed by 2 min of conditioning of 20 mg/L pine oil. Flotation

US3911076A Process for purifying molybdenite

When the molybdenite concentrate contains nonoxidized metal impurities of such metals, e.g., copper sulfides, the impurities are converted to oxidized metal impurities in-situ in the suspension by...

A novel approach for preferential flotation recovery of

01/10/2012 While the molybdenum circuit tailing was treated by a copper flotation circuit to obtain a high recovery of other co-present metal values. (2) The industrial flotation results demonstrated that the preferential Mo flotation approach obtained an excellent cleaner concentrate contained 0.655% Mo with 88.49% Mo recovery in the molybdenum circuit

Recovery and purification of molybdenum from Ni–Mo ore

01/06/2010 So we choose resin D314 to enrich molybdenum from the purified solution. In order to improve the resin adsorption capacity, the purifying solution was acidified by H 2 SO 4 according to the following reation (Neková and Schrötterová, 2000): (1) 7MoO 4 2− + (8 + n)H + → Mo 7 O 24 − n (OH) n (6−n)− + 4H 2 O(n = 0,1,2)

Recovery and purification of molybdenum from Ni–Mo

01/06/2010 A direct hydrometallurgical process for molybdenum extraction and recovery from a Ni–Mo ore is reported. The novel technology includes leaching molybdenum by air oxidation in alkaline solution,purifying the leach solution with freshly precipitated “nascent” Fe(OH) 3 and “buffer agent” NaHCO 3, enriching molybdenum by ion exchange and crystallizing ammonium molybdate tetrahydrate.

Extractive Metallurgy of Non-Ferrous Metals: Part Two

Molybdenum occurs naturally as the molybdenite (MoS2) mineral and is recovered by a flotation process as a primary concentrate at molybdenum mines and as a byproduct concentrate at copper mines. The concentrate is roasted to a technical-grade molybdic oxide (tech oxide) in multiple-hearth roasters. About 80 percent of the tech oxide is sold, in this state or after conversion to

High Purity Molybdenum Disulfide MoS2 Powder CAS

About Molybdenum Disulfide MoS2 Powder: Molybdenum disulfide (or molybdenum) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS2. Like most mineral salts, MoS2 has a high melting point but begins to sublime at a relatively low 450ºC. This property is useful for purifying compounds.
