My process is applicable to all galena ores which do not contain too much readily soluble material such as calcite It recovers practically all the lead and silver in the galena and also the silver not held by the galena if it is in the form of sulphide or antimonide
The process in which galena is smelted requires two important chemical reactions to occur within the furnace 1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide  Roasting is a method where a sulfide ore (ie an ore containing PbS) is heated in air which converts the metal sulfide to either .
Your galena would need to be the sole mineral in your 'ore' I think You likely can only answer all those questions be laboratory testing Do you need to recovery your galena coarse to use it instead of ferrosilicon in a heavy media separation (sink/float) plant? If your galena is coarse grained, it will still jump out of a flotation cell

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 spac
Nov 17, 2008· Extraction Process For Pb and Zn from Galena (PbS) and Sphalerite (ZnS) Or In the world, usually Galena ore (PbS) is found together with Sphalerite ore (ZnS) in sulfide mineral The Grade of PbS and ZnS in the ore between 2-8% for PbS and 8-16 % for ZnS Generally, to increase the concentration of the metal in sulfide mineral is used The .
Galena is by far the greatest ore of lead The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest tim Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver Because of this, silverrich Galena is also an ore of .
Galena is the main ore of lead, used since ancient timBecause of its somewhat low melting point, it was easy to liberate by smeltingIt typically forms in low-temperature sedimentary deposits In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenueIn these deposits significant amounts of silver occur as included silver sulfide .
The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue The association of the minerals and gangue requires a 65 mesh .
So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology That appears to leave froth flotation as still the best method of recovering the gold from pyritic or Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with .
Tailings are the waste material from the ore processing phase, and often contain toxins left over from the ore separating process along with small amounts of heavy metals that were not fully removed Lead is almost always contained in sulfide ores as galena, or lead sulfide 45 Waste rock material from mines that contain metal sulfides can lead .
Galena is a very important mineral because it serves as an ore for most of the world's lead production It is also a significant ore of silver Galena has very few uses beyond its service as an ore, but that should not diminish its importance to society
Galena Lead Ore Processing Galena is kind of lead mineral with big density 74-76g/cm3 and gangue density of 22-3g/cm3 Its big embedded granule and density difference makes gravity a great beneficiation method to gain high grade galena concentrate
