Separator magnetic circuit

[samulon]

Hello, I am looking for a paper that explains how to build a magnetic separator. This separator will be used in a mineral factory over a conveyor belt and the ferromagnetic particles are at least 0.5 Kg weight. I also know that i have to place the rectangular magnets inside a iron "box" but i don´t know much more.
Im grateful for any help.

Thank you very much.
