Mineral processing consumes significant power, primarily in comminution, as well as significant amounts of water through hold-up in conventional tailings facilities. Reducing power and water consumption in comminution circuits can contribute to reduced operating costs and improved sustainability. Me...

Abstract
The comminution energy curve is a profoundly simple graphical technique that displays detailed operating efficiency information for industrial comminution processes. The database underlying the methodology has recently more than doubled, to now contain a substantial fraction of the interna...

Abstract
As the stirrer speed directly affects the motion of grinding media, and hence the interactions with material particles to be ground, the rotation speed of a stirred mill is well recognised as one of the most important factors affecting the grinding performance.
In this work, the effec...

Abstract
Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. In the context of the mining industry, interest in stirred milling technologies has grown over the last 20 years where the typical observation reported in the literatu...

ABSTRACT
The stirred milling of nickel laterites offers possibilities for improving liberation and selective size reduction of soft nickel-bearing minerals in laterites. Batch grinding tests were performed in a netzsch™ lME4 stirred mill on siliceous goethitic, goethitic, and saprolitic nickel la...
