TECHNOLOGY  Centralised control rooms at processing plants and mine sites are already the norm in a modern, technology-driven mine. where scrap material that was previously considered uneconomical to recycle, has now become viable. In 2017 the recycling of REE magnets was not considered due to the monopoly, but China’s steady supply to the market means that now REE minerals have been weaponised in the global trade war. Recycling is also more energy-efficient, for example only 5% of the energy is required to recycle the same volume of aluminium, compared to producing it from raw materials. The need to be able to recycle rechargeable batteries was recognised early on, with collection points and recycling centres already on the cards for when the currently produced batteries will reach the end of their serviceable lives and is expected to have reached the critical mass to make recycling economically viable. Virtual Reality The up takers of virtual reality (VR) or augmented reality has been limited to an extent to training and education institutions. Universities have started using VR to simulate underground conditions and conduct practical training on these platforms. Mines have tested proof-of-concepts were incident investigations are done by using laser survey scan point-cloud data to reconstruct events on the VR platform, limiting the need to access the area where an incident such as a fall-of-ground took place. EPCM companies have also realised the potential of using VR to offer clients project interaction. VR models are used to generate walk-through environments that depict milestone and anticipated final product appearance. 3D modelling the market being flooded with modelling software and being highly skilled in software packages and programming is now a requirement for even the most junior of positions. Exploration remains the main vertical market for 3D-modelling, with the aim of integrating more information from less fieldwork and fewer analyses but producing more accurate models. 3D-modelling has also gained interest as a tool to anticipate risk areas and develop remedial scenarios. Ground truthing will however remain a critical function. Cybersecurity There is a risk factor associated with the introduction of these technologies. The two main concerns relate to the cybersecurity risks of the shift to cloud-based storage and the ‘bring your own device’ culture that is increasingly being adopted by companies. Company IT infrastructure could become vulnerable as it can increasingly be accessed from outside the company network, due to employees with varying degrees of e-safety awareness. It also increases the risk of corporate espionage or sabotage by competitors.  About the Author Dr Nicolaas Steenkamp has almost two decades post- qualification experience in the geological and geotechnical industry.
