Vale's dry concentration pilot holds tailings promise
2020-7-16 Vale's dry concentration pilot holds tailings promise. Brazilian mining firm Vale has launched a pilot plant that performs dry magnetic concentration of low-grade ore using rare earth magnets, reducing the need for potentially dangerous wet tailings dams. Currently the company produces 60% of iron ore using natural moisture.

Separation analysis of dry high intensity induced roll
2014-9-1 A dry induced roll magnetic separator is simple and efficient for upgrading the magnetic mineral and materials. Weak paramagnetic minerals can be effectively removed from an ore by maintaining the field intensity up to ~ 2.5 T,.IRMS as shown in the Fig. 1 consists of a horse-shoe magnet faced by an iron bridge bar and of two rolls, one opposite each pole.
