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 …
First the lead ore is ground into small salt-like particles. Following this, the flotation process takes place which involves mixing the powdered lead ore with water, the addition of pine oil and the introduction of air bubbles and agitation forms a froth of oil containing the lead ore, on the surface.

Lead smelting and lead alloy classification; Lead mining; Lead metal can be classified as either primary or secondary. Primary lead is produced directly from mined lead ore whereas secondary lead is produced from scrap lead products (such as automobile batteries) which have been recycled.
The lead-copper concentrate also contains the major part of the gold and silver values present in the ore. The high gold recovery possible by a flowsheet of this type is augmented by the Mineral Jig which recovers the coarse free gold. The amalgamation residue, which is high grade lead, is combined with the lead-copper flotation concentrate in the thickener.

The overall process from lead ore to very pure lead is quite complicated and lead ores contain other valuable metals like silver, so there more stages in the process than are described here. The social, economic and environmental impacts of exploiting metal ores are discussed on a separate page.
Lead is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials.
Lead bullion contains many other metallic impurities including antimony, arsenic, copper, tin and zinc. 12.3 Primary Copper Smelting In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
lead ore extraction process. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
A major and primary Lead mineral is galena (chemical formula = PbS) which Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in contains carbon and is essential in the extraction of metals from their oxides .
Metallurgy of Lead: Ores, Properties, Extraction, Purification, Uses Extraction: Lead is mainly extracted from the sulphide ore galena. Galena contains lead sulphide and small quantities of silver.
Flotation of Lead Ore. By far the most important lead mineral is the sulphide, galena. In many of the ores in which it occurs it is associated with sphalerite or marmatite, and two-stage selective flotation is necessary to separate the two classes of minerals.
