Under the surface: How AI and GenAI are transforming the end-to-end mining landscape

When asked to describe the “mine of the future,” people generally think of one where every aspect of operations is seamlessly intertwined with artificial intelligence (AI). In the mine, you imagine autonomous drones over the pits, computer vision models monitoring ore extraction and handling, and AI-driven robots performing precise drilling and blasting. In the processing plants, AI-based recommendation systems improve the efficiency of mineral separation techniques, constantly learning and adapting to changing conditions. Across the mine site, deep learning algorithms monitor machinery to predict and help prevent failures and optimize maintenance scheduling to minimize downtime.

But the reality is that this vision is not a distant dream but an unfolding reality. According to various industry reports, the mining sector stands to gain over $370 billion in additional value annually by implementing AI and automation technologies, with AI alone capable of increasing productivity by up to 20%. One study found that AI-powered predictive maintenance could reduce equipment downtime by as much as 30%, while also extending the life cycle of machinery. In the realm of ore sorting, AI technologies have shown a 15% to 20% improvement in resource recovery rates. As these technologies continue to evolve, AI and GenAI will only deepen their footprint in the mining sector, enhancing efficiency and driving the industry toward a more sustainable and economically viable future.

AI and GenAI use-cases across the mine

The picture drawn at the start of this article is accurate at a high level, but that is exactly what it is: a high-level picture. Under the surface, there are several smaller AI and GenAI systems that can be developed across the entire end-to-end process cycle of any mine. These models/systems come together to create an intelligent ecosystem for how the entire mine operates in the most reliable, efficient, and profitable manner. But it is important to have a more detailed view on what these use-cases can be within each part of the mine, and the underlying technical methodologies that enable these use-cases.

Exploration

AI-driven ore exploration: AI algorithms analyze geological, geophysical, and geochemical data to identify potential ore deposits. Machine learning (ML) models classify and predict mineralization zones based on historical and remote sensing data.

Geological pattern recognition: Deep learning models, such as convolutional neural networks (CNNs), detect complex geological patterns in seismic data, satellite imagery, and other geospatial data, aiding in the prediction of mineral locations.

Predictive resource estimation: Ensemble learning techniques model and predict mineral deposit sizes and grades, improving the efficiency of drilling locations and reducing costs.

Concentration plant

Ore sorting and material characterization: Computer vision models process images from ore sorting systems to identify ore composition and quality, improving the efficiency of material handling.

Flotation process optimization: Combination of predictive algorithms and optimization models predict and adjust key flotation parameters such as reagent type, pH levels, and airflow to maximize mineral recovery.

Energy and reagent consumption optimization: AI systems use optimization algorithms to balance energy and reagent usage in the plant, improving the cost-effectiveness of mineral processing.

Drilling and blasting

Ore blend optimization: Metaheuristic optimization models (such as Genetic Algorithms) help optimize ore blending by considering ore quality and quantity, leading to efficient and consistent extraction.

Material tracing: Predictive models analyze real-time material characteristics (e.g., hardness and mineralogy) to predict ore movement and assist with targeted blasting strategies.

Optimized fragmentation and blasting: Reinforcement learning (RL) models adjust blast parameters such as charge size and hole placement in real time to optimize fragmentation while minimizing waste and energy usage.

Loading and hauling

Autonomous fleet management: Autonomous haul trucks learn optimal routing, speed, and load balancing for efficient material transport across the mine site, optimizing traffic, congestion, and fuel consumption.

Load optimization: AI models dynamically adjust loading parameters to minimize haulage costs while maximizing payloads and minimizing fuel consumption.

Cross functional and across the mine

Predictive maintenance: Predictive machine learning models analyze sensor data to track equipment degradation, predict failures, and reduce downtime.

Maintenance advisor: GenAI-based agents trained on equipment manuals, maintenance procedures, and any other documentation, allowing for maintenance personnel to interact with it in a conversational manner to extract information effectively while conducting maintenance.

Technology is the unlock, but adoption is needed for true impact

As organizations march onto their journey to adopt these technologies, they will need to overcome challenges related to adoption and culture change. Building a robust change management program is essential to ensure that the benefits of AI and GenAI are fully realized. This journey towards widespread adoption of these technologies will involve continuous learning and adaptation. Organizations must invest in upskilling their workforce, developing the necessary technological infrastructure, and establishing governance and risk management processes. By doing so, they can unlock the full potential and drive significant improvements using these technological advancements.

In conclusion, AI and GenAI are set to revolutionize the mining industry by enabling new levels of efficiency and innovation. The applications are diverse, have potential to be highly impactful, and it is only a matter of time until that “mine of the future” will just be every mine of today.
