X-ray lead plate lead sheet
Lead is one of the earliest human use of metal, 3,000 BC, humans smelting lead from the ore. Lead and zinc in nature, particularly in primary deposit symbiotic extremely close. They have in common a source of minerals and geochemical behavior is very similar, have similar outer electron structure, have a strong affinity to sulfur and form the same soluble complex. Cases they adsorbed ferromanganese quality, clay or organic matter is also very similar. The average content of lead in the earth's crust is about 15 × 10-6, the average zinc content in the crust is about 80 × 10-6.
At present, it has been found in the earth's crust are about 250 kinds of lead and zinc was about 1/3 of sulfides and sulfates, but only 17 are presently available for industrial use. Among them, the lead industrial minerals, galena, boulangerite, jamesonite, bournonite, white lead, lead alum, chromium lead, pyromorphite, arsenic Galena, Galena vanadium, molybdenum, lead mine; zinc industry minerals are sphalerite, wurtzite, calamine, hemimorphite, silicon zinc, zinc water. Galena, sphalerite and other major industrial smelting of lead and zinc mineral raw materials.
Mainly for the manufacture of lead-acid batteries, the acid for industrial and metallurgical industry lead, lead pipe lined protective equipment, electrical industry lead cable sheathing used and blown fuse. Tin, antimony, lead alloy type used for printing, for the manufacture of pewter fusible lead electrode, and a lead-plated stereotype plates used in the construction industry. Lead on X-rays and γ-rays with good absorbency, widely used as the protective material X-ray machines and nuclear devices. Lead poisoning due to the economic and other reasons, certain areas of lead have been or will be replaced by other materials
