Iron Ore Mining Magnetic separator project using electromagnets

Thanks for answering. That puts you at a disadvantage in your yield doesn't it? Unless your ore is very rich.

yes its true that mag seps work better when wet, but we have an abundant supply of ore at around 40% FE, so dont need to beneficiate so much to reach export grade 63%
What we want the 5000 gausss for is to pull out the lower grade FE from the reject material after we can recovered the high grade 63%.
Any help in the design of the EM much appreciated..

While this link isn't for a magnetic separator, it does give some information about a high strength EM. The guy that wrote it was the inventor of some thing that is in use across the world every day, Magnabend. A magnetic sheet metal bending break. https://www.aaybee.com.au/Magnabend/Building Your Own Magnabend.html

You may be able to get some information and ideas from his EM design calculations.
