Galena ore mineral processing process technology and Galena ore beneficiation plant. Galena (PbS), galena minerals, equiaxed crystal system, space group Fm3m, which also can contain up to 1% silver. Galena a cubic crystal form, aggregation usually granular or compact massive.
The mine is currently producing silver-copper ore at a rate of approximately 625 tons per day. Ore grades are approximately 24.0 ounces per ton silver and 0.76% copper. The present day Galena Mine is an underground silver-copper mine and is served by two vertical shafts.
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.
Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.
May 20, 2010· I have thought that this process is possible in a cheap and moderately difficult process. I have no intention of roasting the sulfides to get at the lead so this is the process I have put together based on information I have read: Crush and sort the ore with gold pan thankyou to the person above suggestion - or heavy liquids.
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 (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either ...
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.
