An alternate model incorporating angle of inclination too has been developed (Asomah, 1996; Asomah and Napier-Munn, 1996). Combining the first industrial database on cyclones generated at JKMRC (Rao, 1966) with his own laboratory data, Plitt (1976) developed an alternative general-purpose cyclone model.
netite media (Davis and Napier-Munn, 1987) and with FeSi media (Napier-Munn, 1984), using density tracers to determine the cut-den-sity. A common (though not very complete) measure of DMC inefficiency is the Ep, defined as: = − Ep δδ 2 75 25 (4) where δ 75 and δ 25 are the densities corresponding to mass recoveries of 75% and 25% ...

Cost will always be the first focus of attention (capex and opex). As power costs rise, and where power is in short supply, there is an incentive to innovate in process design to mitigate these effects. Fig. 2 shows the Australian mining industry multifactor productivity for the last 28 years. The rise up to 2002 was due mainly to improvements in technology and …

It is shown that metal recovery in mineral processing plants is often linearly correlated with feed or concentrate grade, particularly in flotation. ... recovery was the performance criterion. Figure 7 shows the two regression lines (trial and normal), and the relevant statistics are compared in Table 2. ... REFERENCES Napier-Munn, T.J ...
The role of applied statistics has long presented an opportunity in mineral processing, both at laboratory scale in flotation testing, and at plant scale with trials such as …
The applications of computationally assisted modelling to the mineral processing industry started from the early 90s (Napier-Munn and Lynch, 1992; Schwarz, 1991). Computer simulation and modelling gradually proved to be a powerful tool in mineral processing research because of the rapid development of computer technology and new simulation ...
Abstract The influence of angle of hydrocyclone inclination on its cut size was studied in a specially designed laboratory rig equipped with a 75 mm Krebs cyclone.
Section snippets A Brief history. The invention of the DMC and its subsequent history is related in Napier-Munn et al. (2013). The accepted mythology is that the DMC was 'discovered' in about 1939 by Dutch State Mines (DSM) in Holland when a hydrocyclone processing loess (a clay medium) for a dense medium bath in coal cleaning blocked.
Professor Tim Napier-Munn has published a book entitled Statistical Methods for Mineral Engineers: How to design Experiments and Analyse Data. Note one copy of the book is provided to each participant as part of the face-to-face open course registration.

In mineral processing of hard ores, ore particles smaller than 50 microns are defined as fines in this article, because such small particles, especially smaller than 20 microns, are often difficult to concentrate using modern processing technology (Wills and Napier-Munn 2006). 4.2 Weight Percentage of Fines from Blasting
Flotation kinetics modelling statistics The grade-recovery curves, in the form of enrichment ratio-recovery curves, were modelled after Bruey ( Napier-Munn, 2012) in Eq. (5), although the model ...
In the standard JKMRC drop-weight testing approach (Napier-Munn et al, 1996), 15 sets of particles from five size fractions are broken, each at three energy levels (see Table 2), and the product of each set is collected and sized by screening.The degree of fragmentation or the breakage function of an ore is described by the 't n-family' of curves (Narayanan, 1985, …
