First Extractive Metallurgy Operators' Conference Proceedings 2005

The intention of this 2005 conference was to provide a forum for extractive metallurgy operators to discuss and present experiences in dealing with real processing issues and their solutions. The three main aims of the conference were to exchange practical information to assist operators in improving their plant’s day to day performance; to introduce new processing concepts and stimulate debate about how to improve the industry generally; and to review past performance on the implementation of projects from an operator’s perspective with the aim of identifying what was done well and what needs to be done better in the future. All papers were peer reviewed prior to publication in accordance with the AusIMM guidelines to ensure the presentation and technical content is maintained at a high standard. This conference volume will serve as a valuable source of information for those seeking to understand and to further improve plant performance. Content: Front Matter • Table of Contents •Section 1.
