In conventional base metal milling throughput always trumps recovery for maximizing revenue. This has been demonstrated over and over again. TPD also trumps energy efficiency, especially when the pla...

A complex analysis at a pilot plant scale is very hard to duplicate in actual production. I'm not sure you can avoid the trial and error method. The bottom line is the kilowatt hours per ton required to achieve maximum recovery. Several SAG mills ha...

Very interesting topic here. I missed your presentation at IMPC so I will take a closer look to the paper. It is strange to see opposite direction (increase or decrease ball size) to increase SAG thro...

A LIBS On-Stream-Analyzer VS XRF- X-Ray OSA On-Stream-Analyzer are similar in that they are used for elemental analysis, but LIBS can measure the light elements where XRF struggles. LIBS are generally much faster in all cases, an analysis can ...

Compare Lebedinsky GOK and Stoilensky not entirely correct. Because 70% of the concentrate obtained LGOK 7-8 stages of magnetic separation (mineral processing plant + secondary benefication plant) and...
