The effect of pulp chemistry and the presence of solids on a froth bubble size measurement method developed by Bhondayi and Moys (2014) was tested. Three conditions representing different pulp chemistries and two solids loading conditions were invest

In this work, the effect of a froth baffle on flotation performance is investigated both experimentally and numerically. Flotation experiments with an artificial ore comprised of 80% silica as gangue and 20% limestone as floatable component were carr

The growing trend towards ultrafine milling makes it worthwhile to study the effect of key variables on this process. The concept of the “grinding zone” is defined and analysed. It is found that (volume of grinding zone)/(volume of voids between

This paper describes a methodology to monitor axial mixing in an IsaMill as a function of mill feed flow rate, mill tip speed and media load. Steady state temperature measurements (profiles) along the mill length were used to quantify the degree of m

A flotation cell that enables the study of the effects of different air distribution profiles on flotation performance has been designed. Three distinct gas fluxes viz. high gas flux at the back of the flotation cell (impeller and gas distribution me

An electro-resistivity technique for measuring a proxy for froth bubble sizes as a function of height above the pulp–froth interface has been developed. Froth phase bubble size measurements were performed in a laboratory mini-flotation column. Comp

The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the vol
