Unearthing hidden value using pre-concentration techniques

2018 went in a flash and here we are in 2019! To open the new year, we have a thought-provoking editorial from Peter McCarthy and articles on autonomous haulage in OP mines and pre-concentration techniques. Enjoy!

Editorial February 2019: What is acceptable?

The ages of human development – stone, bronze, iron and maybe silicon – are defined by the geological, mining and metallurgical skills people developed. We work constantly to improve our technologies for the benefit of this society and that of future generations. We are part of a great global industry.

Advice to mining industry graduates

It is scary to look back and find a quarter of a century has passed since I graduated. However, during that time, I have ridden a camel in the Sudan, worked on the deepest mine in the world, driven in a tank across the steppes of Russia, tracked gorillas in Uganda, travelled to more countries than I would have ever dreamed possible, and met and married my true love and life partner.

Process automation – drill planning and budget optimization

Often the first budget item to be cut in times of austerity is exploration drilling. We will not go into the wisdom or consequences of this decision, but rather look at a means to optimize the money available for ongoing drilling. Most geologists who have had to do drill hole layouts will have come up with any number of tools or process automations through scripts or macros that help them design a reasonable drill plan in an acceptable time frame. One such approach is described in this article.

Considerations when implementing autonomous haulage in open cut mining

Although autonomous vehicles have been under development for decades, their productive use in mining is relatively new. As the technology becomes more refined and accessible, it is now more commonplace for new mines, and those with sufficient remaining mine life to consider running an Autonomous Haulage System (AHS).

Whole-of-mine optimization and geometallurgy

Geometallurgy may be defined as the integration of geological, geotechnical, mining, metallurgical, environmental, and economic information to provide a platform to increase the net present value of a deposit.

Kriging – Do you know what samples are being used

In the late 1970s to early 1980s Ordinary Kriging (OK) became the block grade estimation method of choice. This was mainly due to it being an unbiased estimation method that attempts to minimize the extension (estimation) variance of the estimate.

Video: The Optimized Fleet in Action

On 19 July 2018, AMC Consultants' Kobus Potgieter, Business Improvement Manager, presented the last installment of Austmine's "Optimising the Mining Fleet Webinar Series" focusing on the optimized fleet in action. Kobus was joined by Stephen Williams, Managing Director, Concerto Analytics in a panel discussion on the topic.
