A major and primary Lead mineral is galena (PbS) which comprises of 866% of lead In order to smelt this mineral, a blast furnace is needed to be used A blast furnace is an enormous oven which is used to accomplish the smelting process According to their properties and applications, lead alloys can be classified into: corrosion resistant alloys, battery alloys, solder alloys, .
Solvent extraction of Pb(II) and Zn(II) from a Nigerian ,
From Fig 3a, the extraction of Pb(II) increased progressively with increasing pH from 10 to 50, after which there was a slight decline in the percent of Pb(II) extractedThis could be attributed to the formation of higher lead hydroxide complexes and thus could apparently explain the loss in Pb(II) extraction ,
Lead processing, preparation of the ore for use in various products Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury) Its low melting point of 327 °C (621 °F), coupled with its easy

The extraction rate of lead from galena increased sharply initially and slowed down as the experiment progressed This behavior may be attributed to reaction progressing initially, followed by the formation of a sulfur layer and reaction becoming important There ,
Lead extraction was 96 pct when galena concentrates were leached in recycled waste fluosilicic acid using hydrogen peroxide and lead dioxide as oxidants After solid-liquid separation to obtain the lead-fluosilicate solution and the residue containing elemental sulfur, pure lead metal was electrowon in a 20-liter cell containing four titanium .
How lead is made - material, used, processing, product ,
The pure form of galena contains only lead and sulfur, but it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic Two other minerals commercially mined for lead are cerussite and anglesite Over 95% of all lead mined is derived from one of these three minerals
Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteri Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ,
