Sometimes they are sufficient to separate minerals for use, like coal or iron ore. But more often the element that we are looking for is found as a chemical compound, and so will have to be separated by further chemical reactions.
These processes include crushing, grinding, smelting, and refining, which are necessary to separate the valuable elements or minerals from the ore matrix. The extracted metals or minerals are then further processed to meet specific industrial requirements. It is important to note that not all minerals are ores, but all ores are minerals. Ores ...

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
