Over 10 recent years, fine grinding technologies have been used with increasing frequency for mineral processing in the mining industry. It can be explained by the fact that ore bodies are getting increasingly complex with disseminated mineralization requiring finer grind for maximum mineral recovery. In April 2012, Outotec presented its new Outotec HIGmill fine grinding technology solution for mineral processing companies. HIGmill technology has proved to be very efficient for ultra fine grinding of limestone and some other industrial minerals.
