First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt. Next the lead powder is put through a flotation process, that involves mixing the lead ore with water, the addition of pine oil and the introduction of air bubbles and agitation which forms an oil froth, containing the lead ore, on the surface.

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 regarded as a silver ore and called argentiferous galena. Sphalerite is zinc sulfide, but may contain iron. Black sphalerite may contain as much as 18 percent iron. Lead Ore The lead produced from lead ore is a soft, flexible and ductile metal. It is bluishwhite, very dense, and has a low melting point.

Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.
