results, it says. Upon completion of the transaction, Allison will be able to offer a wider range of commercial-duty powertrain and industrial solutions to more customers and end users worldwide.
“ This acquisition marks a transformative milestone in our commitment to empowering our current and future customers with propulsion and drivetrain solutions that Improve the Way the World Works,” David Graziosi, Allison Transmission Chair and CEO, said.“ We look forward to harnessing this momentum to increase value for all of our stakeholders worldwide.”
Dana’ s Off-Highway business operates in over 25 countries and serves a global customer base supported by approximately 11,000 employees. Providing solutions for a wide range of applications in construction, forestry, agriculture, specialty, aftermarket, industrial and mining segments, this business is recognised for its powertrain technologies, encompassing axles, propulsion solutions and drivetrain components.
Additionally, Dana specialises in hybrid and electric drive systems tailored to customer needs and is further distinguished by its global network of manufacturing facilities and technical centers, Allison said.
At MINExpo 2024, Dana showcased solutions that it said advanced the electrification of mobile mining equipment, including a low-emission series hybrid powertrain system for underground loaders; a zero-emission drivetrain solution for underground drill rigs; the introduction of an integrated fan solution for alignmentfree Brevini EvoMax ® helical and bevelhelical gearboxes used in mining conveyor applications; and a Dana Brevini planetary gearbox supplying torque ranges up to 2,200 kNm for apron feeders, roller presses and other applications.
R. Bruce McDonald, Dana Chair and CEO, said:“ Dana’ s off-highway business has long been committed to delivering innovative solutions for off-highway applications, and we are confident that under Allison’ s ownership, the team will be well-positioned to continue that legacy. This agreement represents a strategic opportunity to ensure the ongoing
6 success of the business, while allowing Dana to focus on our core priorities. We look forward to seeing the off-highway business thrive under Allison’ s leadership.” www. allisontransmission. com www. dana. com / markets / off-highway
TOMRA Mining takes next AIpowered ore sorting step
TOMRA Mining has launched CONTAIN™, a solution that, it says, represents the next breakthrough in AI-powered ore sorting.
By analysing X-ray imagery in real time, CONTAIN identifies visual patterns that traditional sorting systems miss, giving operators precise control to optimise sorting to their specific needs, the company says.
The proprietary deep learning technology is designed to enhance the recovery of inclusion-type ores that are difficult to detect using traditional sorting methods.
Developed entirely in-house by TOMRA’ s software engineers and mining experts, CONTAIN uses convolutional neural networks to perform real-time analysis of X-ray imagery, visually classifying rocks based on the probability of subsurface ore mineral inclusions.
“ Our system was trained on tens of thousands of ore samples and designed from the ground up for sorting inclusion-type ores,” Stefan Jürgensen, Software Team Lead at TOMRA Mining, says.“ With CONTAIN, operators can dynamically adjust the grade-recovery threshold via a touchscreen interface, enabling precise control over yield and product specifications.”
TOMRA says it has been a pioneer in applying AI to the field of sensor-based sorting for decades, with CONTAIN building on this foundation with targeted classification of inclusion-type ores – pushing the boundaries of automated sorting decision making.
Unlike traditional optical sorting systems, which often have limitations in detecting low-grade or inclusion-type ores, CONTAIN introduces a fundamentally different approach to classification. By analysing the structure of each rock using advanced deep learning algorithms, the system identifies subtle mineralogical patterns that indicate the presence of valuable metals such as tungsten, nickel or tin. Each rock is assigned a probability score based on its likelihood of containing mineralisation below the surface, enabling precise, data-driven sorting decisions. This capability allows mining operations to adapt their strategies in real time – whether the goal is to maximise concentrate grade, minimise valuable material loss, or align with processing cost constraints.
CONTAIN is built for industrial-scale performance, TOMRA claims. Because it does not rely on specific throughput or spacing on the belt, the system maintains pinpoint accuracy even in dense, fastpaced input streams. This makes CONTAIN especially effective in high-volume processing plants where consistency, speed and recovery rates are critical to profitability.
CONTAIN has been engineered to handle a wide spectrum of ore grades – from highvalue deposits to low-grade, inclusion-rich rocks that have historically been difficult to process efficiently. Conventional sorting systems can be configured to detect some low-grade material, but they tend to let large volumes of gangue enter the product stream, diluting output and eroding profitability. By contrast, CONTAIN uses deep learning to classify mineralisations with exceptional accuracy, enabling precise sorting thresholds
that make the recovery of low-grade ores economically viable, TOMRA says.
Jürgensen added:“ Existing technologies can be configured to detect low-grade material in such ores, but this results in a high quantity of waste rocks being sorted into the product stream, diluting the product beyond economic viability. CONTAIN is exceptionally accurate in evaluating the value of a rock, making sorting thresholds for such relatively low-grade ores economically viable.”
Field trials at Wolfram Bergbau in Mittersill, Austria, confirmed the transformative potential of CONTAIN, according to TOMRA.
Integrated alongside TOMRA’ s latest COM XRT and OBTAIN technologies, the system delivered immediate performance gains. The operation rapidly increased total plant throughput by 8 %, achieved a 33 % reduction in ore mineral losses and recorded its lowest-ever tails grade. The visual impact of the improvements was so striking within the first minutes of operation that the team immediately requested a second installation. www. tomra. com / mining; www. wolfram. at
