Lead is mined in over 40 countries, but half of the world's output comes from the USA, Canada, Russia, Kazakhstan, Uzbekistan, Canada, and Australia. Ore is recovered by blasting then dumping, followed by crushing and finally hoisting to the surface for treatment. In mining, the ore is extracted by drilling or blasting and then crushed and ground.

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.
