Thanks to technology like Google Maps and drone photography, most of us are only a few clicks away from a glimpse of life on the other side of the planet. You can take a tour of Beijing’s Forbidden City, watch a Spanish street party, or get a panoramic view of Dubai in real time – without even getting up from your chair! Our communities have never been so connected, and the benefits to society are incredible.
But beyond the camera frame, our world is vast and can be very inhospitable. As easily accessible mining deposits run low and ore grades diminish, the mining industry has two courses of action available: to increase efficiency at brownfield sites dramatically, or to explore greenfield sites not yet mined. The best option, of course, is to do both – and that is what we see happening in the industry today.
Mining companies are beginning to look at locations known to contain mineral deposits that have been ‘put off’ until now due to their remoteness or difficulty of access. Sites that would have been considered an unjustifiable expense a few decades ago are now the next logical step, whether in the Australian desert, under the Greenland ice, or deep underwater. But despite advances in technology, these sites remain difficult (and expensive) to access.
As a mining company, it can be understandably hard to find highly skilled employees who are willing to make the move to these locations, and recruitment is only half the battle. Once you have a team, you have to train them, insure them, fly them back and forth, and keep them supplied with necessities for as long as they are needed. It’s expensive – and time-consuming.
In today’s regulatory landscape, you also need to ensure that you are mining as sustainably as possible. A larger headcount makes this more difficult day-to-day, but the good news is that designing a new mine from the ground up to run with fewer employees is much easier than reducing the numbers at a current site.
The hyper-connection that can easily make us forget the wildness of our planet also offers a solution to these challenges. On-line, real-time materials analysis is already revolutionizing process control from the mine and stockpile to the furnace, thanks to next-generation analyzers like the CNA cross-belt family.
Alone, these individual instruments are already a powerful lever to increase efficiency and drive sustainability. But when combined within a holistic, customized system of automated processes, they can work in harmony to create a fully automated laboratory that reduces costs and eliminates human error.
Automated laboratories can take care of every step, from sample preparation and transport to analysis and results reporting, with only a small core team necessary to resolve issues and maintain the system. Samples can be moved around via pneumatic tube for longer distances, with robots to prepare samples through dilution, fusion, grinding or any other method needed before placing them into sample holders. With experiments repeated exactly every time results are significantly more consistent, and throughput is many times higher than in manual labs.
In one case study, agricultural chemical company Yara's fully automated laboratory installed in Finland, led to a more than 12 times increase in the number of analysis, boost the recovery rate and dramatically improving efficiency and lowering running costs in the laboratory by more than 3 million Euro per year.
And that’s not all: another key industry trend that builds on the automated lab is data analysis in the cloud. Once results from various instruments and sensors are reported into one centralized platform, there is no need to have your expert staff on-site to analyze the data. Remote access to data stored in the cloud opens your analytical process to anywhere in the world, and software automation is an easy addition to refine data analysis further where human input is not needed.
From this point, it’s not such a large step to using this rich data for predictive purposes – not only reacting to samples of ore already mined, but also using real-time sensor information to direct automated mining operations based on AI and machine learning. This promises to save energy, waste, and much more. While full-scale operation of this technology may be some years away, it is key for mining companies to anticipate it today as the industry takes its place at the front line of sustainable reform.
Even without imagining a sci-fi scenario in which robots take control, it’s easy to see where safety could be a concern in a mine with fewer people – but safety is usually significantly improved by having a smaller team on-site. Aside from the fact that a lab without humans will naturally be a lab without accidents, the next generation of instruments have much better safety features built in.
As mining companies around the world turn to more remote locations and work toward sustainability, process efficiencies that can be added into existing workflows will not be enough to offset both the carbon and the financial costs involved. New mines must be 'automation-first', with a holistic design that maximizes productivity and minimizes costs.
This will be challenging, but it also represents a great opportunity. Necessity is ‘the mother of invention’, and the industry has an unmissable chance to design its own future by thinking carefully today about how it wants to work tomorrow.
