Galena Lead Ore Processing

Galena is kind of lead mineral with big density 7.4-7.6g/cm3 and gangue density of 2.2-3g/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 dissociated from impurities and jiggers will separate galena granules our from impurities to gain galena concentrate. Finally, high grade concentrate of galena can be gained with a high recovery rate and great beneficiation efficiency.

Lead gravity separator works greatly to gain high grade lead concentrate due to the big specific gravity difference between lead and its gangue. The crude galena is crushed and screened to make galena granules dessociated from its gangue.

Gravity separators like jigging machines can be used to purify lead ore. Machines like crushers, rod mills, jig separators, shaking tables can be involved in lead gravity processing line. The simple crushing breaks the big blocks into small ones while rod mill is used to mill output from crushers to be fine ore of -5mm without any extensive-milling. Galena lead jigging machines 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 shaking table can be used to recover the galena in the tailings to improve the recovery.
