Abstract. Since early 2001, Kalgoorlie Consolidated Gold Mines (KCGM) has successfully operated an ultra fine grinding (UFG) circuit to supplement its roaster capacity for the treatment of the refractory gold flotation concentrate. A second UFG mill was installed in 2002 taking the total UFG capacity to over 20tph while grinding to 11-12 ...

The regrinding of some streams within flotation circuits, to liberate valuable mineral attached to gangue, is a common practice. However, the methodologies proposed for flotation circuit design based on optimization, usually, do not consider regrinding. This work analyzes the effect of the uncertainty in flotation and regrinding stages on the ...

The stirred mills, recently introduced to mineral processing, have proved to be more energy efficient than tumbling mills in terms of fine grinding, and have been extensively used in many mineral processing plants at the regrinding stage (Gao et al., 2002, Jankovic, 2003, Pease et al., 2006). In contrast to tumbling mills, where motion is ...

About the Author. The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
