A fundamental investigation on the breakage of a bed

A fundamental investigation on the breakage of a bed of PGM ore particles: An attainable region approach, part 2 The ore was cone and quartered and then screened into the required feed size, ranging from 850 to 1400 m using a stack of sieves. H. IpekEffect of Grinding Media Shapes on Breakage Parameters. Part. Part. Syst. Charact., 24

In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix....

2017-2-12 · of 24 m and maximum size of 25 m in the PGM ores [16]. This requires a very fine grinding to liberate all the PGMs locked in the silicates, which would lead consequently to the chromite being ground even finer. The current standard cir-cuit design to concentrate PGMs from the UG2 ore consists of a mill-float/mill

The majority of the PGM's in the UG2 ore are in the silicates and thus the PGM distribution results would indicate the amount of breakage in the silicate fraction. Cr 2 O 3

Binary modelling the milling of UG2 ore using a matrix

The matrix modelling approach was successfully used by Choi et al. to estimate the individual milling parameters of ZnS and gangue of a sphalerite ore. A similar approach was used by Herbst et al. to develop a multi-component-multi-size liberation model of a copper ore.
