What You Need To Know About Mineral Processing

Comminution is the most energyintensive stage in mineral processing To make this step more energy efficient, Sepro is working with a team of researchers to develop a system that uses powerful bursts of microwaves to help sort the valuable minerals from waste prior to grinding The process also creates microfractures in the ore, requiring less energy for future grinding
