IRON MINING TODAY Open pit mining for iron ore replaced shaft mining very early on in the history of the Michigan Iron Ranges. Today, all the underground mines are closed, and only a very few open pit mines are still operating. What remains of the underground mines is often only a few heaps of waste rocks (below) and some slumped landscapes.

Effect of Bentonite on the Pelleting Properties of Iron ...

The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.


iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO 2 and Al 2 O

Processes for phosphorus removal from iron ore - a review

2.2.1 Chemical Processes. Acid leaching has been considered as an alternative to flotation for removing phosphorus from iron ore. Technologically, the leaching process is a simpler way to treat the fine-particle sinter feed without the restrictions that are necessary in flotation.
