Ferrosilicon Atomised Milled

Can Milled and Atomized Ferrosilicon cut a mining company’s costs in half?

The commodity boom is growing at top speed and ore bodies are getting wiped out. As mining companies are exploiting these economically recoverable rocks, only inferior bodies are left for the rest to use.

How to use less capital equipment and lower operational cost in your mining company:

What everyone’s not telling you!

Milled and atomized Ferrosilicon uses much less capital equipment and the operational cost is cheaper.

Milled and Atomized Ferrosilicon is an accepted medium for the gravity separation of minerals, aggregates and metals with a specific gravity of approximately 2.0 to 4.0.

Dense medium separation (DMS) is a process where a suspension of dense powder in water is used to form a type of ‘heavier liquid’ to separate mineral particles in a sink-float process. Many modern dense media plants use this because it is so profitable.

Atomised FeSi: Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70
Milled FeSi: 65D, 100D, 150D, 270D, 270F

Why Milled Ferrosilicon is profitable

The reason why Milled and Atomized Ferrosilicon is profitable is because it makes easily accessible ore worth more than it would be worth otherwise. Your production costs will also be drastically reduced because the development cost per ton of metal produced is much less.

The best way to apply Dense Medium Ferrosilicon in your system is by contacting DMS Powders. The production of milled ferrosilicon in South Africa dates back to 1949 and DMS Powders is the largest supplier of milled ferrosilicon in the world.

The benefits of using DMS Powders for you plant or mine:
