galena lead ore beneficiation concentration upgrading washing plant

详情

Galena is kind of lead sulfide with its big density 7.**7.6g/cm3 and gangue density of 2.**3g/cm3. Its big embedded granule and density difference makes gravity a great beneficiation method to gain high grade galena concentrate. For gravity separation of galena, the separator involved is mainly jigger. After crushing, the galena granules will be dessociated from impurities and jiggers will separate the galena granules our from impurities to gain galena concentrate.Finally, the high grade concentrate of galena can be gained with a high recovery rate and great beneficiation efficiency. 
Galena gravity upgrading works greatly to gain high grade galena lead concentrate on basis of big specific gravity difference between galena and its gangue. The crude galena is crushed and screened to make the galena granules liberated from its gangue. Kind of gravity separators like jigging machine can be used to purify the galena to get galena concentrate and tailings. Machines like crushers, rod mills, jig separators, shaking tables can be involved in galena gravity processing flow sheet. The simple crushing breaks the big blocks into small ones while rod mill, as kind of milling equipment, is used to mill the crushed output to be fine of *5mm without any extensive-milling. Galena lead jig machine can be involved to enrich the milled galena to get the final concentrate and tailings. There shall be some fine granules in the tailings from jigger, so a shaking table can be used to recover the galena in the tailings to improve the recovery.
