Introduction to Mineral Processing. Mineral processing is a field that contends with procedures and technologies used for separating valuable minerals from gangue or waste rock. It is a process that converts the extracted ore through mining activity into a more concentrated material, which serves as an input for the extractive metallurgy.

8.2 Mining and Ore 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 surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1 ). Creating a giant hole in the ground is generally ...

In some mines of Minas Gerais, the average content is 40% Fe in itabirite. To increase its grade, the ore is concentrated through processing with water and the tailings are disposed of in dams. Then, the high-grade ore resulting from this process can be transformed into pellets at the pelletising plants to increase the added value of the product.
