LEAD ORE CONCENTRATION EQUIPMENT

Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated. It was thought that froth floatation separation was a secure beneficiation method for lead ore. But for different ores, different concentration ways shall be adopted to gain the best beneficiation from the lead ore dressing project.

Here is some new type of galena lead ore upgrading machine to gain high grade lead concentrate.

Galena is kind of lead sulfide with its 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 the galena granules out 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 is kind of important lead mineral and gravity separation is usually involved to get galena concentrate when floatation separation is used in some places. More and more galena lead beneficiation factories use gravity separation instead of floatation separation. Here the reasons of gravity separation taking place of floatation can be:

Concentration of Lead Ore

1. For the same capacity, plant investment of gravity separation is much lower than that of floatation separation

2. There is no chemical involved for gravity separation while floatation separation needs different chemicals to get final concentrate.

3. There is a strict requirement about the operation of floatation separation while the gravity separation needs only some people to lubricate some parts.
