  • SAIMM President Isabel Geldenhuys talks to Mining Weekly

    South Africa on verge of nice breakthroughs in hydrogen, says new SAIMM president
    17th August 2021
    By Martin Creamer

    Speaking to Mining Weekly in a Zoom interview, Geldenhuys expressed the view that all the big mines with big moving machinery will have the opportunity to move away from diesel and switch to a hydrogen-based fuel system because of the contained ecosystem. While the use of green hydrogen is always first prize, Geldenhuys pointed out that many processes have grey hydrogen as a byproduct and expressed the view that where grey hydrogen is at the ready, it should be used as an imperfect solution rather than being left to go to waste.

    She said that South Africa had the required hydrogen know-how as a consequence of the Department of Science and Innovation having supported the hydrogen economy concept for nearly 20 years. “What really excites me is the focus on being greener and more efficient," Geldenhuys said. On the multidisciplinary front, she said: "There are many opportunities for us to work together and bring interesting, transdisciplinary thinking into metallurgy to solve our big problems.” Under her leadership, the SAIMM plans to strengthen its online presence so that it can communicate optimally with the rest of the mining and metallurgy world at a time of rising mining fortunes. South Africa’s mining and metallurgy history extends across more than a century, which has resulted in a wealth of knowledge being accessible from SAIMM’s databases.

  • When one tugs on a single thing in nature, one finds it attached to the rest of the world

    Change resistance is the tendency for something to resist change, even when a surprisingly large amount of force is applied. Systemic change resistance is the tendency for a system to reject an attempted change, even though the change is supported over a long period by a substantial fraction of the population. Systems ecologists have increasingly concluded that the conservation of

  • Discovering Rare Earth Elements

    ‘All truths are easy to understand once they are discovered; the point is to discover them.’ – Galileo Galilei With the approaching SAIMM event focusing on rare earth elements (REEs) in October 2021, I have decided to utilize my final address to discuss REEs, which in my opinion remain a potential game-changer in the Southern African mining and industrial landscape. The

    ‘The first step in the evolution of ethics is a sense of solidarity with other human beings.’ –Albert Schweitzer A year ago, I presented on the importance of ethical behaviour and ethical leadership at the Annual General Meeting. I believed this to be particularly relevant, given that South Africans often find themselves in positions of uncertainty and insecurity in our

  • Mine-impacted Water

    South Africa has one of the most prominent mining industries in the world. The country saw a boom in the mining industry in the late 19th century with the drivers being gold and diamond mining, followed soon after by coal mining, then PGM processing. Today, gold, PGMs, and coal mining continue to make significant contributions to the economic and social

Topic: The Pursuit of the Digital Twin in African Mining


Speaker Profile:  Jamie is CEO of pan-African mining technology platform Dwyka Mining Services with offices in South Africa and Botswana. Delivering cutting-edge solutions through the adoption and adaptation to the latest mining technologies with a focus on improving safety, health and environmental conditions, DMS is supporting Africa’s leading miner’s digitalisation journeys across the continent.

Topic info: Digitalization of mining assets into highly visual formats is key to unlocking hidden value by solving a widening skills gap and growing safety mandate. DMS has partnered with global pioneers in the remote sensing and visualization (UI) industry to deliver mixed reality capture and digital twin capabilities that augment mining team’s sight on- and off-site. This session will focus on digital twin developments and how these are applicable in African mining. Drilling down into the detail we will unpack real-world examples and a case study using Emesent’s Hovermap drone for GPS-denied scanning capability used to map the previously inaccessible and deliver ROI for the client.
