5% – but zones that can produce highquality DSO are finite. Thankfully, there are ample resources of iron ore worldwide at lower insitu grades (generally about 2040% Fe), which can be readily enriched during beneficiation processes using gravity or magnetic separation to increase their purity to upward of 65% Fe. In an economically viable operation, the cost of processing the ore can ...

Magnetite is ferrimagnetic, which means it is attracted to a magnet. It is the most magnetic of all the naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of >magnetism. Today it is mined as iron ore.
