Beneficiation Method & Plant for Lead Ore

Lead ore covers lead oxide and lead sulfide and the mainly beneficiation methods are floatation separation and gravity separation. The specific beneficiation method and plant allocation for lead ore depends a lot on the ore nature and structures. Here is some share about lead ore beneficiation from Forui.

Actually, floatation separation can work for all lead ore, but as we all know that floatation separation needs chemical to work and it is not so friendly to environment. However, some other beneficiation methods can also help to get final lead concentrate with the same final concentrate index. E.g, for lead ore of galena with coarse inlay, gravity separation can enrich the lead. However for some lead ore with fine grains, gravity separation does not work to gain the efficiency while flotation separation is a must to get the lead out from the impurities.

Floatation separation makes use of difference of mineral oleophylic natures, and requires a lot about the mineral natures. Floatation separation needs large plant investment, and high productive cost and asks for more about the feeding grade. There is no profit to invest floatation separation for the cutoff grade ore.

Gravity separation makes use of density difference between useful mineral and waste gangue. Gravity separator like shaking table and jigging separator can work on condition that there is density difference between useful mineral and waste gangue and the useful lead granules can be liberated from gangue after crushing and screening.

Lead ore beneficiation flow sheet and plants involved is designed according to the ore natures. Experience can be told, but it can not decide a investment schedule. Here Forui testing platform can supply free test for you if samples about 15-20kgs can be available. And a detailed flow sheet can be designed for you according to the test.
