Selective recovery of lead from galena-sphalerite by ...
Hence, the possibility of selective separation of lead from galena-sphalerite was investigated in this paper. The experimental tests on how the process parameters-the type of dielectric concentration, electrolytic potential, complexing agent, current density, anode material, temperature, stirring speed, and pH affected the electro-oxidation of galena and sphalerite were carried out.

Extracting Lead Materials from Ore
Extracting Lead Materials from Ore. Lead is a dense, soft, low-melting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from ...

EXTRACTION OF LEAD FROM GALENA CONCENTRATES USING ...
A study on lead extraction from lead concentrate had been conducted. Galena is usually associated with other sulfide ores such as sphalerite.The lead concentrate was able to be extracted and purified into its metal through a leaching process using a selective solvent of fluosilicic acid (H 2 SiF 6).Parameters used in this process include ratio (dose) of reactant (H 2 SiF 6:H 2 O 2 ...

How to Make Lead from Galena Concentrates
Using the Bureau's new process, galena concentrates are leached directly under oxidative conditions in waste fluosilicic acid at tem-. peratures less than 120°C. This solubilizes the lead and produces a residue containing elemental sulfur and other metal values. Pure lead metal (99.99 pct) is recovered from the leach solution by ...

Galena Lead Ore Processing - frjigmachine
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. For gravity separation of galena, the separator involved is mainly jigger.
