Beneficiation process of molybdenum ore

Molybdenum ore beneficiation flotation method is mainly recovered in the molybdenum mineral is molybdenite. Sometimes in order to improve the quality of molybdenum concentrates, to remove impurities, to further chemical processing molybdenum concentrate outside the grounds. Molybdenite crystal structure of hexagonal layered or plate by Fan and health along the layer S-Mo-S structure and the layer of polar covalent bond formation of S-Mo. Layers and weak bonding between layers, and layer covalent bonding even stronger. Therefore, the structure of molybdenite layer solution can easily split along the flaky or tabular output, which is the natural floatability chalcocite good reason. Practice has proved that: at the right under the grinding fineness, the dissociation of molybdenite crystals occur in S-Mo-S layer, the S-Mo surface hydrophilic small proportion. But after grinding time, S-Mo surface ratio of increase in the floatability of decline, although at this time adding a certain amount of polarity, such as xanthate collector class is beneficial to the recovery of molybdenite, but after grinding with the new sludge floatation effect. Therefore, the sorting of molybdenite to avoid and prevent excessive wear in the production and the need to adopt multi-stage grinding sub-sorting process, step by step to monomer dissociation, to ensure a high recovery of molybdenum concentrate. Molybdenum mining and processing techniques have been improved continuously since the first mine was started at Climax near Leadville, Colorado in 1916.Today, the principal moly mines, both primary and by-product, are found along the Great Continental Divide of the Americas, in China and in the CIS. Many of these mines are amongst the most productive in the world, with the largest capable of moving over 50,000 tonnes of ore per day. Mining and processing plants are operated with minimum emissions under stringent environmental protection regulations.

Deep select contain trace amounts of copper molybdenum ore, using part of the mixed - flotation process. Jiangtai molybdenum processing plant processing ore valuable mineral molybdenite, pyrite and minor chalcopyrite, molybdenum, copper flotation, tailings flotation of pyrite, copper - molybdenum separation and molybdenum concentrate mixed - flotation process.Now also from the copper-molybdenum ore beneficiation recovery of molybdenum, a commonly used process copper-molybdenum mixed flotation, and then the copper-molybdenum separation and a selection of molybdenum concentrate.

Copper-molybdenum separation and molybdenum concentrate featured commonly used sodium sulfide and sodium cyanide.

The molybdenum concentrate selected depends primarily on the number of total enrichment ratio of molybdenum. General total enrichment is high, the selection of the number of times usually more; total enrichment ratio is low, which offers a selection of the number of times usually less. Molybdenum processing plant ore processing ore grade higher (0.2% to 0.3%), enrichment ratio of 133 to 155, its original design featured a total number of 7 times, Jiangtai processing plant molybdenum processed raw ore grade of approximately 0.1%, the enrichment ratio of 430 to 520, and advice total number of up to 12 times. In recent years, in order to meet the needs of molybdenum concentrate exports, Jiangtai molybdenum processing plant using hydrochloric acid - ferric chloride leaching Apart from impurities in the molybdenum concentrate.
Molybdenum ore dressing plant from some of colored system point of view, the processing of ore grade vary greatly, the high at 0.3% or more, a low of 0.1% or less, and some only 0.02%. Processing the actual recovery of the vast majority of more than 80%. The resulting concentrate grade of 45% to 54%, tailings grade of 0.02%, a high of 0.04%, a low of 0.01%.
The current industrial production of molybdenum molybdenite concentrate smelting oxidizing roasting to extract pure molybdenum trioxide restore roasting molybdenum metal powder three links.
Molybdenum concentrate first reverberatory furnace, multiple hearth furnace roaster oxidizing roasting or flash furnace desulfurization made a calcine impure molybdenum trioxide (Mo ≥ 40% ~ 48%), Calcine using The metal thermal or silicon thermal method can produce molybdenum ferroalloy.

Technological process of Molybdenum Ore Processing plant/ Molybdenum ore beneficiation equipment:

 1. Use the jaw crusher to break the molybdenum ores to the required fineness and then convey them via the elevator to the storage bin.

2. Feed the crushed minerals to the ball mill for further grinding.

3. After being ground, the super fine ores enter the spiral classifier to be cleaned and graded.

4. Through the mixing tank, the ores are processed in the flotation separator. Add proper flotation agent will help to separate the fine particle molybdenum ores.

5. Remove the water content in the final molybdenum concentrate by using the high efficient concentrator.
