Mining and Metals in a Changing World  

The transition to clean energy starts beneath the surface. From lithium in EV batteries to copper in solar panels, mining provides the essential materials needed to power a more sustainable future. But navigating the pace, scale, and complexity of this shift requires a partner with both strategic vision and technical expertise.   

As the world’s trusted infrastructure consulting firm and a leader in sustainability, AECOM is committed to accelerating the clean energy transition. With global expertise spanning engineering and environmental solutions for the design, development, and operation of mining and mineral processing projects, we tailor our approach to each clients’ unique needs.  

We understand that environmental, social, economic, and geopolitical factors all play a critical role in shaping project timelines, costs and overall success. The resources sector is searching for new ways to meet these challenges to optimize production, reduce costs, and adopt new technologies to improve operations while managing the effects of climate change. Clients can leverage our support from the earliest stages, allowing us to collaborate on how to minimize regulatory delays and environmental compliance costs.  

Mining Services Throughout the Project Life Cycle  

For more than 120 years, AECOM professionals have served the minerals industry in planning, permitting, designing, building and supporting operations for metal/mineral processing facilities around the world.   

Our full range of services spans the entire project lifecycle — from concept to detailed design; engineering and project management for execution and commissioning phases; as well as decommissioning and closure of existing operations. The demand for fast ramp-up, production reliability and maximized returns to stakeholders must be balanced with safe and efficient closure, demolition and rehabilitation of the environment to its pre-operational state at the end of each facility’s lifecycle.
