A system for dry recovery of fines and superfines of iron ore, characterized in that the recovery is carried out in a totally dry metallurgical route, provided with a drying means with mechanical stirring, at least one set of cy- clones for air-sorting of fed material; and magnetic dryer by a permanent- magnets roll arranged at an inclination ....

#### How can I calculate the relative permeability of iron?

As you don't know the purity of the iron, I don't think you can calculate the permeability Therefore, if you are not going to buy another core with known properties, you should measure the properties of the existing one, for example, by using the core in the electromagnet:-) If the properties of the test electromagnet are not satisfactory, you can redesign the coil based on the test results...
