Overview

 

A primary form of academic output is through publications in peer-reviewed journals and conference proceedings. The table below lists the number of publications from 2011 to 2016. The Minerals to Metals team has produced 34 peer-reviewed journal articles over the six years in question, at a steady rate without great fluctuations. Over the same period 30 papers were produced in conference proceedings.

In the technical field many research projects are undertaken for more than academic purposes. In order for interested parties, whether sponsors, industry, government or the public, to have access to the results of the research, technical reports must be produced. Some of these, such as those written for the WRC, are published widely, while others remain ‘in house’ reports. Eleven of these reports have been produced since 2011, with seven of these clustered into 2016 alone. It is too early to tell whether this represents a trend or not. Chapters in books is a much smaller arena for publication, with just one chapter associated with MtM over the six years.

Because MtM places such emphasis on collaboration and interaction beyond the core of the initiative, presentations of all kinds and academic conference presentations in particular are a cornerstone of the dissemination strategy. The years 2011 to 2016 have seen 56 oral presentations and 23 poster presentations bearing the MtM logo. 

It is important to note that the MtM philosophy ensures that at least half of the journal articles and conference proceedings have a student as first author, and most have representation from more than one research group among the authors.

Lately, a number of academics have been invited to speak at international and national events about their MtM related research, particularly in the areas of mine waste, education and sustainable development, and heap leaching.
