Prior to mining, all rocks contained in a mineral deposit must be placed in one of several categories known as ore types. Each ore type describes a different way that the rock will behave in processing. The ore type determines which process stream a particular mined unit will be sent to, sets expectations for process engineers and …

The mining techniques for lead typically depend on the deposit type. Open-pit mining is often used for large surface deposits, while underground mining is applied to deeper ore bodies. The extraction process includes drilling, blasting, and processing the ore through concentration methods like flotation, followed by smelting and refining.
