Refining minerals Mining of mineral resources

There are many different methods used to concentrate and refine minerals. The choice of methods depends on the composition of the ore. Most of the methods however, make use of chemistry to extract the metal from the compound or remove impurities from the final product. We will discuss the extraction of iron from iron ore as an example.
