Case Study: AI Transformation at Freeport-McMoRan

Freeport-McMoRan, a major player in the global copper mining industry, is harnessing AI and robotics to enhance copper production from its existing assets, anticipating a surge in global demand for copper. In a strategic move, the company partnered with Gecko Robotics, utilizing their advanced robotic systems to collect critical operational data that feeds into machine-learning algorithms. This approach aligns with Freeport’s broader goal of increasing efficiency and addressing declining ore grades through technology, minimizing the need for large-scale new capital investments. This AI initiative is part of Freeport’s long-term strategy to optimize its assets and extend their lifespan while ensuring environmental sustainability.

Key Takeaways

• Freeport-McMoRan is using AI and robotics to optimize mining operations and address declining head grades in copper mining.
• One of its many initiatives is a partnership with Gecko Robotics where Freeport employs robots to collect crucial data, feeding machine-learning algorithms that enhance productivity and safety.
• The AI transformation led to significant production increases and cost savings, demonstrating that existing assets can be optimized without the need for major new capital expenditures.
• By reducing equipment failures and forced outages, the AI initiative also contributes to lower emissions and improved safety standards.

Approach

To enhance production and efficiency without substantial new capital investments, Freeport-McMoRan embarked on an AI-driven transformation journey. One of its many initiatives is a partnership with Gecko Robotics, which specializes in deploying robots to collect detailed operational data. The collected data is analyzed through machine-learning models to optimize various aspects of mining operations.

The numerous initiatives undertaken by Freeport not only target productivity gains but also aim to reduce equipment failures and extend the lifespan of aging assets, thereby minimizing the need for new infrastructure. The pilot program, initially launched at the Bagdad mine in Arizona, was designed to test the effectiveness of AI models in improving throughput and recovery rates. By integrating advanced analytics and cross-functional teams of engineers, metallurgists, and operators, Freeport aimed to build a scalable solution that could be deployed across its other sites in the Americas.

Implementation

Freeport McMoRan’s AI transformation began many years ago to gather critical operational data. This data, integrated into the company’s centralized systems, was used to develop AI models designed to optimize copper recovery and production processes. At the Bagdad mine, a cross-functional team collaborated to pilot the AI solution, focusing on increasing mill throughput and copper recovery. The pilot’s success led to the development of the Throughput-Recovery-Optimization-Intelligence (TROI) model, which recommended real-time adjustments to processing parameters, resulting in notable production gains.

Scaling this success across other sites required a centralized data architecture and cloud-based solutions to standardize data collection and model deployment. Freeport also employed agile methodologies, forming cross-disciplinary teams that worked in short sprints to iterate and improve AI models rapidly. By upskilling internal talent, including engineers and metallurgists, and bringing in external experts, Freeport built a robust AI capability to sustain and expand its transformation program.

Results

The AI initiative led to impressive gains for Freeport-McMoRan, particularly at its Bagdad mine, where copper production increased by 5%. The mine’s throughput exceeded 85,000 tons of ore per day—10% more than the previous quarter—while its copper recovery rate improved by 1%. These improvements translated into significant cost savings, with the AI system saving $300 to $400 million in potential capital expenses that would have been required for building new concentrators.

The system-wide implementation of AI models is projected to yield an additional 200 million pounds of copper per year, generating $350–$500 million in EBITDA. Moreover, by proactively addressing equipment failures and minimizing forced outages, Freeport’s AI initiative also contributed to reduced emissions and enhanced safety measures, aligning with the company’s sustainability and operational efficiency goals.

Challenges and Barriers

Despite the success of its AI program, Freeport-McMoRan faced several challenges. Attracting and retaining the necessary AI talent was a significant hurdle. To overcome this, the company adopted a “buy, build, and borrow” strategy, upskilling internal talent while supplementing its workforce with external experts. Another challenge was adapting AI models to different sites, as each location had unique operational requirements.

Freeport addressed this by developing modular AI tools that could be tailored to specific site conditions, leveraging reusable code to streamline the process. Additionally, the shift to an agile operating model required cultural and managerial changes, which were addressed by involving operators and metallurgists in AI development teams, fostering collaboration and building trust in the new technology.

Future Outlook

Freeport-McMoRan’s successful deployment of AI in its concentrator optimization program positions the company to extend its AI capabilities further. Future initiatives are likely to target capital project execution, maintenance, and leaching operations, using the AI and agile methodologies honed in the “Americas Concentrator” program. As Freeport continues to optimize its operations and reduce emissions, it aims to become a model for AI-driven transformation in the mining industry.
