Finer Grind Sizes Now a Necessity for Mineral Recovery

The demand for ore bodies is on the rise, however ore grades are decreasing around the world. In order to recover the maximum amount of minerals and a high grade, finer grind sizes will be needed.

The ore industry is having to tackle the challenge of increasingly complex ore bodies as well as the need for increased energy efficiency. One possible solution is the High Intensity Grinding (HIG) mill that is designed specifically for complex and fine grain ore.

The HIG technology has been around for over 30 years however it has just recently been considered for the mineral processing industry.

Compared to traditional ball mills, the HIG mill saves as much as 40 – 50% more energy. Along with this, the HIG mill is proving to be more compact and simple to install, adaptable to various grinding applications and simpler to maintain.

Ultimately, HIG technology enables more advanced and energy efficient grinding for the complex ore bodies that are becoming commonplace in the industry.
