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 froth flotation
separation and gravity separation. Flotation separation makes use of
its floatability to get high grade galena concentrate. Flotation 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, flotation 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 flotation
separation. So galena lead ore gravity upgrading will be the leading
beneficiation method instead of flotation 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 separator,
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.
JXSC 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 kg can be
available.
