molybdenum flotation

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. The rougher concentrate can be upgraded to a marketable grade molybdenum concentrate at between 77 to 80% overall molybdenum recovery. Regrinding of the rougher concentrate is required in order to achieve target final concentrate grade.The sample tested was a bulk grab sample and as such is unlikely to be a true representation of the resource.

This Molybdenum Flotationmetallurgical program consisted of performing one rougher and four batch cleaner flotation tests on the sample of sulphide ore. The nominal primary grind P80 selected for this series of tests was 150m. The cleaner tests were designed to investigate the effect of a regrind stage between rougher and cleaner flotation. Here above you see the laboratory flowsheet, test conditions and the grade-recovery curves for the four cleaner tests. In considering the results achieved in the single rougher test and the data presented, the following points of interest are noted:

The feed and test products for test 1 were assayed for molybdenum oxide and approximately 6% of the molybdenum in the feed was present as molybdenum oxide. The metallurgical balance for test 1 indicates that 91.4% of the oxide was lost to the final tailing. Tests 2 and 3, which did not have a regrind stage between the rougher and cleaner circuit, did not produce a marketable grade concentrate. The final concentrate grade in these tests averaged about 22% by weight molybdenum at 85% recovery of molybdenum into the final concentrate. Tests 4 and 5, which included a regrind stage between the rougher and cleaner circuit, did produce an acceptable final concentrate product. The average results from these tests suggest that the mineralized sample can be upgraded to produce a concentrate containing about 50% molybdenum by weight. At this grade, recovery of molybdenum was determined to range between 77 to 80%.

Beneficiation process will vary according to differences between the types of ore , ore sorting the following is a common method of introduction: Select iron : 1 , ore crushing ; 2 , grinding process ; 3 , sorting technology ; 4 , sintered pellet technology ; Select Manganese : Mechanical election ( including beneficiation , screening , re-election , strong magnetic separation and flotation ) , and vice- set fire , chemical beneficiation method. Select Chrome : Firstly jump titanium machine, shaker , spiral concentrator , centrifugal concentrator and sorting belt chute , the force of the water also sorting . Vanadium titanium magnetite : is it after a period of grinding, a coarse , a fine , sweeping away the magnetic separation process to elect the magnetotail magnetic magnetite concentrate after performed . COPPER : flotation , magnetic separation, re-election or hydrometallurgical methods and so on. Select lead and zinc : general magnetic - floating , heavy - floating , heavy - Magnetic - Floating other joint beneficiation methods. Choice of aluminum : general use hand-selected . Select aluminum equipment includes magnetic separator, ball mill , conveyor, magnetic roller, iron absorption , magnets, electromagnets and so on. Select Nickel: 1 , flotation ; 2, using crushing, screening and other processes in advance to remove the differentiation of weak , low bulk nickel bedrock . Select Cobalt : Average flotation . Select tungsten : tungsten mineral divided by ore type wolframite and scheelite . Beneficiation methods are hand-selected , re-election , flotation , magnetic separation, electrostatic separation , and other methods . Select the tin : gravity beneficiation beneficiation , flotation process . Molybdenum : mainly flotation. Select Mercury : There are hand-selected , re-election and flotation , which is widely used and most effective flotation . Select Antimony : There are hand-selected , re-election , flotation and other methods. Select platinum group : 1 , reasonable milling , using appropriate cyclone classification ; 2 , recoveries ; With gold : gold in the ore content is very low, you need to extract gold ore crushing and grinding and beneficiation methods to separate the gold . Mainly re-election and flotation . Select Silver : 1 , flotation ; 2 , a single flotation and floating - joint process re-election law , cyanidation of flotation , flotation which is most important. Lithium , tantalum , niobium , beryllium election : Hand election law , flotation , chemical or chemical - combined flotation method, enthusiastic election law , election law radioactivity , grain float beneficiation method. Strontium election : heavy stone lapis lazuli community beneficiation method most commonly used , the most common structure for the process to jigging - shaker as the main flow. Selected rare earth metals : general use magnetic separation, flotation concentrate containing about 60% to get rare earth oxides

[Improvement]: Cone impeller is equipped with the vanes sloping backward at a certain angle, which makes strong agitation ability and simple structure. The impeller chamber is equipped with multi holes cyinder air distributor. Adpot the U-shaped tank with little sand sediment.

KYF air inflation floatation cell working principle: when theflotation cellis at work, the rotation of impeller makes the slurry all around via tank bottom absorbed from downside of impelle into inner-vanes of impeller, where low pressure air produced by the blower goes into via hollow shaft and the air distributor of impeller chamber at the same time. After fully mixture of the slurry and air among vanes, they are pushed out in inclined upward direction from upper half of the impeller around, and go into the tank via steady f\ow and orientation by the stator. Air bubbles rise to the foam stability area, and after concentration process, the froths overflow from the overflow weir into the froth tank. Another part of the slurry flows to ward the lower part of impeller, then through the impeller agitation, they are mixed together to form mineral laden bubbles again, and the rest of the slurry will flow to the next tank to become tailings eventually.
