This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size of the concentrate was P80 = 46 µm and the main species present were quartz (%), dolomite (%), pyrite (%), arsenopyrite (%) and 112 g/t gold. After optimizing hydrated lime and lead nitrate additions, standard cyanidation ...

Abstract. Comminution in stirred media mills is a frequently applied topdown method towards the production of micron and submicron particles. However, due to the high energy density, this type of mill is appropriate for mechanical activation (MA) as well. Despite the vast field of mechanochemistry which encompasses an increase in reactivity ...

Run the IsaMill™ empty (no water or media) for 510 minutes to warm up the bearings and seal. Then proceed to run the mill empty at 1500rpm for an additional 10 minutes and measure the cumulative power draw using the watthour meter (Wh) and stop watch. From the time and total energy values, the no load power draw can be calculated.
