BHP’s Chile Infrastructure Sale Signals a New Era for Asset-Light Mining and Water Recovery

BHP’s reported plan to divest its desalination plant and high-voltage transmission assets in northern Chile reflects more than a capital recycling strategy—it highlights a broader transformation across the global mining industry. As major miners increasingly adopt asset-light operating models, investment is shifting toward core mining production, efficiency improvement, and sustainable resource utilization.

For decades, mining companies preferred to own every part of their operations, including water supply systems, power infrastructure, ports, and processing facilities. Today, the focus is changing. By transferring infrastructure assets to specialized operators while securing long-term service agreements, mining companies can reduce capital expenditure, improve return on investment, and concentrate financial resources on expanding strategic mineral production such as copper.

This trend also creates new opportunities for advanced mineral processing technologies. As water becomes an increasingly valuable resource—especially in regions such as Chile's Atacama Desert—efficient solid-liquid separation is no longer simply an operational advantage but a strategic requirement.

At KERTE Filter Press, we believe filtration technology plays a critical role in supporting this transformation. High-performance dewatering systems help mining companies recover process water, reduce freshwater consumption, and lower operating costs while meeting increasingly strict environmental and ESG requirements.

KERTE filter presses are designed for demanding mining applications, including copper concentrates, tailings, lithium projects, iron ore, coal, and other mineral processing operations. With optimized filtration performance, our systems can achieve water recovery rates of up to 80% while producing filter cake moisture as low as 10%, depending on the material and operating conditions. Recovering more process water not only reduces dependence on external water infrastructure but also improves overall plant efficiency and supports sustainable mine operations.

As mining companies continue to prioritize productivity and capital efficiency, reliable filtration equipment becomes an essential investment. Efficient dewatering minimizes tailings volume, lowers transportation costs, reduces storage requirements, and enables greater recycling of valuable process water throughout the production cycle.

The industry's shift toward specialized infrastructure ownership does not reduce the importance of water management—it makes efficient water utilization even more critical. Whether a mine owns its water supply assets or purchases water through long-term agreements, maximizing every cubic meter of water remains a key competitive advantage.

As global demand for copper continues to grow alongside the energy transition, mining companies will increasingly seek technologies that deliver higher productivity with lower environmental impact. KERTE Filter Press remains committed to providing advanced filtration solutions that help mining operators improve resource efficiency, optimize water recovery, and build more sustainable, future-ready mining operations.
