The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains 86.6% lead.
Lead miners continued to enjoy what appeared to be a limitless supply of ore. In 1841 estimates were made that four times as much lead ore was mined than had been seen in the preceding four years. Much of the mining between 1833 and 1856 was called "surface scratching" referring to the lack of tunneling.
