US3672579A

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

What Are the Uses of Magnetite? (with picture)

Magnetite has been known to mankind since early history and led to the earliest discovery and understanding of magnetism. It is the most highly magnetic naturally occurring mineral, and the variety known as lodestone was the basis for the first crude magnetic compasses. Today, there are many uses of magnetite, such as for abrasives and coatings.
