Lead Concentrate for Sale

It is a silvery-gray crystalline solid substance. It is insoluble in water and denser than water.  It easily penetrates the soil to contaminate groundwater and nearby waterways. Contact may mildly irritate skin, eyes, and mucous membranes. It may be mildly toxic by ingestion, inhalation and skin absorption. 

Lead can be produced pyro-metallurgically or hydro-metallurgically, depending on the type of ore used as a charge. In the pyro-metallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Ores with a mixture of lead and zinc concentrate usually have lower respective metal concentrations. During sintering, a blast of hot air or oxygen is used to oxidize the sulfur present in the feed to sulfur dioxide (SO2). Blast furnaces are used in conventional processes for reduction and refining of lead compounds to produce lead.

Application

  The single most important commercial use of lead is in the manufacture of lead-acid storage batteries. It is also used in alloys such as fusible metals, antifriction metals, solder, type metal, alloy of lead with antimony, tin, and sometimes copper. Shot lead is an alloy of lead, antimony, and arsenic. Lead foil is made with lead alloys. Lead is used for covering cables and as a lining for laboratory sinks, tanks, and the "chambers" in the lead-chamber process for the manufacture of sulfuric acid. It is used extensively in plumbing, piping systems inside buildings for water supply and sewage. Because it has excellent vibration-dampening characteristics, lead is often used to support heavy machinery. Lead is also employed as protective shielding against X rays and radiation from nuclear reactors. Lead has many commonly used compounds and is used to make other chemicals.
