The primary breakage properties of rocks such a strength (σ) and elastic moduli (i.e. Young's modulus (E) and Poisson's ratio (ѵ)) are not usually characterised at comminution scale. Traditional comminution tests such as the Bond Work Index grindin

A number of previous researchers have noticed that the degree of mineral liberation in a given size fraction is the same regardless of where in a comminution circuit a sample is collected. This behaviour has been observed for a range of ore types, an

The powerful modern toolbox of hybrid Process Mineralogy for flowsheet development uses best practice sampling as one of its tools. In this paper, the three key components of best practice sampling are reviewed with case studies. These three componen

A method for rapid evaluation of processing behaviour based on assessment of the heterogeneity of ore texture extracted from drill core images is described in this paper. The method involves three stages - drill core scanning in a hyperspectral scann

The heuristic of a constant liberation by size independent of the degree of comminution has been established as a robust assumption over time. Therefore, when assessing the comminution circuit performance, achieving a final target P80 size at the low

Mineral liberation is a key step in many mineral processing flow sheets and is achieved by breaking large pieces of ore into smaller particles which are suitable for the subsequent separation process. The ore being broken consists of mineral grains w

The influence of two alkaline pH modifiers, namely sodium hydroxide and calcium hydroxide was investigated to evaluate and compare their effectiveness in pyrite rougher flotation of a refractory gold ore with a high sulfide sulfur grade (13% S2-), us

Current tests for characterising rock breakage in comminution do not allow decoupling of rock breakage properties from the machine environment. Furthermore, it is difficult to predict the comminution behaviour of different ores or how they might beha

Measurements of ore particle composition distribution, commonly termed mineral liberation distribution, are used in assessing process performance in mineral processing. In many applications, comparisons are made between particle composition distribut
