Across the mining industry, three challenges stand above the rest.

Across the mining industry, three challenges stand above the rest. First, operators must process significantly more ore to achieve the same metal production targets. As ore grades continue to show high variance or even decline at sites around the world, concentrators are under pressure to increase throughput without compromising reliability or safety. 

Secondly, energy and water consumption have become critical operational concerns. Grinding alone is one of the most energy-intensive steps in mineral processing, while water scarcity is affecting mines in regions around the world. 

Thirdly, plants are being challenged to recover more value from each ton of ore. Even small improvements in recovery can have a major impact on profitability, particularly when valuable minerals are still being lost to tailings. 

The future of mineral processing will be defined by technologies across the flowsheet that help operations move more material, use fewer resources, and recover more metal from every ton mined.

Redefining performance across the circuit 

To face these industry wide challenges, it is important to consider how innovations can be leveraged to redefine performance at critical stages of the flowsheet. The key is to look at how new technologies and offerings can impact each stage of the flowsheet and to further explore what these changes can mean to the entire processing circuit. New technology used at one process step can impact downstream equipment and processes so taking a holistic view is critical to optimizing performance. For example, grinding technologies such as vertical roller mills, which use a combination of compressive and shear forces, can lead to improved mineral liberation, which in turn can result in to up to 7% better flotation performance. 

Increasing throughput: Metso Primarok™ gyratory crusher 

The entire process plant depends on the performance of the primary crusher. If throughput is constrained at the front end, the rest of the plant cannot reach its potential. The new Metso Primarok™ gyratory crusher was designed specifically to maximize primary crushing performance. Its optimized kinematics, refined crushing chamber and increased stroke helps to ensure reliable performance and high availability, while its large feed acceptance (up to 1,425 mm) supports maximizing throughput with a wide capacity range of 1,500 - 20,000 metric tons per hour. For operations processing lower-grade ore, the ability to move more tons through the plant can be a significant competitive advantage. 

The design also incorporates advanced automation and maintenance features that reduce downtime and support safer operation and service work. One key service feature is that the crusher's wedge concaves are removable using hydraulic cylinders, which eliminates in-situ flame cutting.  

Improving energy and water efficiency: Metso Loesche VRM 

Grinding remains one of the largest consumers of energy in a concentrator. That makes comminution efficiency a key priority for mining companies focused on both costs and sustainability. The Metso Loesche Vertical Roller Mill (VRM) introduces a fundamentally different approach. By combining crushing, grinding, classification, and material transport into a single unit, the VRM simplifies flowsheets while significantly reducing resource consumption. The technology can reduce energy use by up to 40% compared with traditional (semi-autogenous ball mill and crusher (SABC) circuits, operate in fully dry or reduced-water processes, eliminate grinding media requirements, and deliver an exceptionally high reduction ratio exceeding 3000:1. The result is a more compact, lower-energy grinding solution that aligns with the industry's growing focus on sustainable mineral processing. 

Increasing recovery: Sampo™ Cell 

Recovering more value from ore is increasingly important as mines seek to maximize returns from existing deposits. The Sampo™ Cell is Metso’s next-generation coarse particle flotation technology, designed to recover valuable minerals at coarser particle sizes and unlock value that might otherwise be lost to tailings. By enabling coarser grinding, the technology can help reduce grinding energy requirements while increasing plant capacity and lowering water consumption. Most importantly, the Sampo™ Cell provides a new approach to recovering value from coarse, partially liberated particles helping mining operations make more of the ore they process. 

Driving better decisions with data 

Digital technologies have become essential to achieving consistent performance in modern concentrators. One challenge many operations face is not a lack of data but rather converting that data into practical actions that improve production. That is where novel solutions such as Metso Digital Production Management and Metso Data-driven Performance Analytics come into play.  

Metso Digital Production Management uses operational data, planning information, and simulation models to rapidly evaluate production scenarios and recommend optimized operating strategies. This helps sites respond more effectively to changing ore characteristics, process conditions, and production targets.  

Meanwhile, Metso Data-driven Performance Analytics continuously evaluates equipment and process performance, identifying bottlenecks, performance gaps, and improvement opportunities. Supported by Metso experts and advanced analytics, the service helps operations achieve higher throughput, improved recovery, and more stable performance. In short, AI and advanced analytics are helping operators move from reactive decision-making toward predictive and proactive optimization.

The future of minerals processing  

The future is not about a single breakthrough technology. It is about finding the right combination of technologies for each orebody, operating environment, and business objective. For one operation, the optimal solution may combine a high-capacity primary crusher such as Primarok™ with advanced digital production management solutions. For another, the greatest value may come from combining a VRM grinding circuit with coarse particle flotation using Sampo™ Cell to reduce energy consumption and maximize recovery. 

"There is no silver bullet that will solve all minerals production challenges", states Juan Frausto, Sales manager for Metso.  

Juan is also a recent recipient of the 2025 CEEC Medal for Operations and Design as joint author of the paper "Extending the dry processing route" covering the growing importance of technologies such as VRM that can reduce water requirements and support more efficient mineral production. "We always need to consider the ore properties as well as the specific applications and should not fear considering different configurations outside of conventional circuits. Some examples could be hybrid flotation circuits, such as pneumatic flotation cells like the Concorde Cell™ in combination with conventional flotation technology. Another example could be early adoption of VRM technologies for single product or dual product outcomes in combination with coarse particle recovery, which could also be an important option to explore specific applications,” he continues.   

In the end, the most successful operations will be those that take a whole-flowsheet approach, integrating equipment, process expertise, AI-powered digital solutions and automation, supported by expert services into a single optimized system. 

As ore grades decline and sustainability expectations increase, the winners will be mines that can process more tons, consume fewer resources, and recover more value. That is where the next generation of mineral processing is heading.
