A range of freely-available tools and learning resources to assist comminution engineers.


In this presentation an historical perspective of the origins of Mine-to-Mill is described and is followed by a discussion of how AG/SAG feed size affects throughput and specific energy and the factors that in turn influence AG/SAG feed size, such as ore hardness, Run of Mine (RoM) size distribution and crusher operation (both primary and secondary). The role of the intermediate stockpile between the primary crusher and AG/SAG mill is also described in terms of how it affects size distribution.  Hitherto unpublish full-scale plant data are used to illustrate various points.

About this series

This is a 3-part series of presentations for Minerals Processors to provide an introduction to the understanding of, and tools necessary to conduct Mine-to-Mill programmes from a blasting and comminution perspective. Its aim is to provide the basics for Minerals Processors to help them achieve a successful outcome.

The 3 parts are entitled:

  1. The influence of feed size on AG/SAG milling
  2. An introduction to blasting
  3. Changing AG/SAG feed size through blasting

As far as possible use is made of data and information from published papers.
