- Lead: resource distribution and production
The content of lead in the Earth's crust is 0.0016%, and the reserves are abundant. Currently, the proven resource volume is more than 2 billion tonnes, and the reserve volume is 89 million tonnes (U.S. Geological Survey-2014). In nature, lead resources exist largely in the form of associated minerals, with the ore deposit containing mainly lead together with the single lead deposits accounting for only 32.2% of the total reserves. The main lead ores are galena (PbS), cerussite (PbCO3 ) and lead sulfate (PbSO4). In addition, a small amount of lead also exists in all kinds of uranium and thorium mines. Lead resource distribution in the world is as follows:
- Area distribution:
- The lead resources in the world are mainly distributed in: Siberia, Russia in Europe; central and western regions of China in Asia; Queensland, Broken Hill , Elura and Woodlawn (New South Wales), Tasmania, and North Bay, MacArthur River in Australia; the southeastern area of Missouri and Mississippi River valley area in the US, and Zacatecas and San Luis Potos in Mexico within North America; and Cerrode Pasco and Morococha in Peru, South America.

- Country distribution:
- The lead reserves are greatest in the following countries: Australia (40%); China (15%); Russia (10%); the United States (5.6%); Peru (8.4%); and Mexico (6%). The lead reserves of these six countries cover 85% of total reserves in the world.

- Trends in global production and use of lead
- Mine production of lead has gone up from about 3.7 million tonnes in 2007 to 5.3 million tonnes in 2013 posting an average annual growth rate of about 6.6% per annum. However, according to the estimates of International Lead and Lead Study Group, Lead refined production has increased only at about 3.0% per annum in the corresponding period to 10.6 million tonnes in 2013. China contributes for about 53.8% of total mine production in the world followed by Australia contributing for about 11.8%.
- In terms of refined production of lead, China is the single largest producer with about 44.3% share followed by U.S. with about 12.4% share, India and South Korea with about 4.3% share eah.
- Major producers and consumers of lead
- Consumption of lead also posted an average annual growth of about 3% per annum during 2007 to 2013 and stood at about 10.6 million tonnes in 2003. China is the largest consumer accounting for about 44.5% of total consumption in the world. U.S., India and South Korea accounted for about 15%, 4.8% and 4% respectively of the world lead consumption in 2012.
