CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

The aim is to remove separate concentrates in a complex ore. This is driven by smelting practice and concentrate contracts which penalise impurities in For example in a lead/zinc sulphide ore the galena can be floated first at higher using cyanide to prevent sphalerite and pyrite from floating. Then activation of sphalerite with copper sulphate ...

benification of galina ore process

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.

Lead (Galena) Facts

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

The ore was crushed to pass a 2.8-mm. screen.

Lead Smelting - Base Metal Smelting

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 [2]. 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 ...
