Variables affecting the fine grinding of minerals using stirred mills

Abstract. Base metal resources are becoming more fine-grained and refractory and minerals separation processes require these ores to be milled to increasingly finer sizes. To cope with very fine grinding to below a P80 of approximately 15 μm stirred milling technology has been adopted from other industries. Neither this.

DIFFERENT TYPES OF MILLS. According to the ways by which motion is imparted to the charge, grinding mills are generally classified into three types: tumbling mills, stirred mills, and vibrating mills. Figure 4: Different types of grinding mills. Tumbling mills: In this mill, the mill shell is rotated and motion is imparted to the.

The development of stirred mills has opened up many new opportunities to recover valuable minerals from refractory ores. Stirred mills have already been reported as an enabling technology for the processing of fine grained ores in lead/zinc applications (Pease, Young and Curry, 2005). Historically, conventional ball mills.

Stirred milling—new comminution technology in the PGM . - SAIMM

Introduction. Stirred milling is the latest comminution technology to be applied widely in the PGM industry. The drivers are related to the shift in the mining and extraction of PGMs from the.
