its color and luster distinguish galena from nearly all minerals but stibnite. from this mineral it is easily distinguished by its more difficult fusibility by its cleavage and by the fact that it does not yield the antimony fumes when heated on charcoal. occurrence localities and origins:
galena group. galena is the primary ore mineral of lead. worked for its lead content as early as 3000 bc it is found in ore veins with sphalerite pyrite chalcopyrite tennantite-tetrahedrite etc. and in skarns as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

galena also called lead glance is the natural mineral form of lead(ii) sulfide (pbs). it is the most important ore of lead and an important source of silver.. galena is one of the most abundant and widely distributed sulfide minerals.it crystallizes in the cubic crystal system often showing octahedral forms. it is often associated with the minerals sphalerite calcite and fluorite
galena is a primary mineral. most of the lead minerals such as cerussite and anglesite are secondary minerals formed from galena. impurities in the structure of galena such as silver and bismuth may change galena's cleavage properties.
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.

what is galena galena is a lead sulfide mineral with a chemical composition of pbs. it is the world's primary ore of lead and is mined from a large number of deposits in many countries. it is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. in sedimentary rocks it occurs as veins breccia cements isolated grains and as replacements of limestone and
the lead telluride mineral has the same crystal structure as galena. within the weathering or oxidation zone galena alters to anglesite (lead sulfate) or lead carbonate. galena processing technology. in order to recover lead out of galena smelting process is required.
