Lead is a weighty, malleable, bluish grey metal. It is also one of the most resistant metals to frequent corrosion problems. The main single use of lead in the present day is in the manufacture of the lead acid storage battery, a very important element of all automobiles. The standard car battery has around ten kilograms of lead. Within the communications industry, lead continues to be used a great amount as protecting sheathing for underground and underwater cables, as well as transoceanic cable systems. There are some lead compounds that are utilized as paint pigments. Red lead or lead oxide is the basic paint primer for iron and steel.
Approximately all lead is acquired from sulphide ores and the most common of these lead minerals is called galena. It is frequently found in combination with added sulphide ores, in most cases those of zinc, as well as those of copper.
Ore bodies that are at or close to the surface are mined by open pit methods. When an ore body takes place at some depth under the surface, it requires being mined through underground methods.
Some of the most important world producers and suppliers of refined lead, in mine production include the United States, China, Germany, the United Kingdom, Japan and Canada. In certain places such as Canada, lead is produced generally as a co product of zinc. Recycling of lead, mostly from scrapped car batteries, is a significant source of refined lead in Canada, on behalf of almost fifty percent of the total refined production. Just around ninety percent of the exports in this country of refined lead are taken to the United States.
