Galena Ore Upgrading Jigging Plant Dressing Machine - China

price: contact company for price

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. Why is gravity

separation adopted for galena enrichment? And what advantages does

gravity separation take over floatation separation, please?

The composition of galena is PbS with its good floatability and specific gravity of 7.4-7.6. So the beneficiation of galena lead ore is floatation separation and gravity separation. Floatation separation makes use of its floatability to get high grade galena concentrate. Floatation beneficiation processing can help to get high enrichment efficiency, but it requires much about the operator with its high plant investment and high operation cost. However, floatation separation can be unfriendly to environment and it has been limited by government, and it will be taken place by gravity separation. Gravity separation has a low requirement about the operator with its small plant investment, and low operation cost. With reasonable plant allocation, the beneficiation efficiency of gravity separation is even better than floatation separation. So galena lead ore gravity upgrading will be the leading beneficiation method instead of floatation separation.

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.

Forui is a manufacturer of kinds of mining machines for beneficiation of placer gold, quartz gold, mercury, barite, fluorite, celestite, pyrite, hematite, manganese, and recovering of smelting alloy from smelting slag of silica-manganese smelting slag, chromite smelting slag, and ferro-nickel smelting slag. Free test can be done for you if samples of 10-20 kgs can be available.
