This paper examines the design of comminution circuits and the issues that impact on comminution circuit efficiency.Circuit efficiency is discussed, principally from the perspective of power efficiency. However, operating efficiency, maintenance efficiency, capital expenditure and return on investme...

The paper examines the current state of equipment and circuit design, with reference to Australian practice. Following a review of the changes in milling applications over the last fifteen years, developments in mill design are examined. Current issues include trunnion versus shell support; drive ty...

ABSTRACT
The Discrete Element Method (DEM) approach is used to simulate flow of granular materials for a variety of mining industry applications. The next step in this approach is to combine several DEM particles into particle clusters using structural bonds and to allow them to break t...

This paper provides some basic guidelines for comminution circuit selection from a range of alternatives. Factors itemised in the decision making matrix include:
Project type and size
Ore characteristics and properties
Circuit cost considerations
Test work costs and impact on project s...

This paper presents observations made during the conduct and analysis of eleven separate autogenous and semi-autogenous pilot plant trials. These trials were conducted using different ores for various projects over the past five years. The ores tested include relatively competent porphyry, diorite,...
