20.1 Metal Deposits – Physical Geology

Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure 20.1). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less ...

How Is Lead Mined? - Reference

Lead is commonly found in deposits with other minerals, such as silver, zinc or copper. Once the lead ore is brought to the surface, it goes through a series of refining processes that separate out the different metals contained in the ore.
