The technologies developed by our in-house team of engineers, application experts and machinists are designed and built to meet the most strenuous demands of recycling. Our sorting systems redefine machine capability and set new standards in performance thanks to our high-precision sensors, data-driven software and powerful processing techniques.

With our cutting-edge technology, you benefit from more flexibility and a dedicated team that knows exactly how to make the most of your sorting system. Our long-standing collaboration with waste and metal recyclers throughout the world is our constant source of inspiration – and the evolution of our technologies continue.

XRT (X-Ray transmission)

X-ray transmission technology enables materials to be recognized and separated based on their specific atomic density. This technology makes it possible to obtain a high purity level in sorting materials regardless of surface moisture or dust coating.

Typical application: It can be used to recover large coated diamonds before secondary crushing.
Color Recognition

Our color cameras identify materials based on their color. Their capabilities go beyond the visible spectrum and include infrared, ultraviolet and other spectra.

Typical application: Our color sensors allow the precise discrimination of low grade and contaminant particles for talc, phosphate and many other application.
VIS (Visual spectometry)

Much more sensitive than the human eye, the VIS sensor is able to recognize all the colors in the visible spectrum for transparent as well as opaque objects.

Typical applications: VIS is used for upgrading industrial minerals.
EM (Electromagnetic sensor)

The highly sensitive EM sensor sorts materials like nickel ores and metal slags based on electromagnetic properties like conductivity and permeability.
Photometry

The photometric (PM) sensor system is based on our monochromatic laser attenuation and photo multiplier reflectancexr measurement technology. The PM sensor sorts based on color, structure, size and shape differences. It is used as a supplementary detector to compliment other sensors in order to distinguish the particles from the backround.

Deep Learning Technologies

OBTAIN™

OBTAIN™ - A groundbreaking deep learning technology for TOMRA's sorters, revolutionizes ore sorting by enabling precise detection and classification of individual particles, even when clustered. OBTAIN™ is an industry-first: single-particle precision in high-throughput ore sorting. This revolutionary software uses a Neuronal Network to identify the properties of each particle accurately and independently of the sorter’s capacity, achieving unparalleled precision and reliability in detection and ejection. Based on their specific requirements, the mining operation has the flexibility to either enhance the throughput of the sorter while maintaining consistent sorting efficiency or improve sorting precision without compromising the existing throughput. It is a true game changer.

CONTAIN™

Industry-first innovation for inclusion-type ore sorting. An AI-powered sorting system that lets you see deeper, sort smarter, and recover more. The future of inclusion-type ore classification. CONTAIN™ is more than an AI-feature - it's a revolution in ore sorting intelligence. By applying deep learning to XRT data, it detects valuable inclusions within rocks even when buried deep inside - revealing what traditional sorting can't. Most sorting systems work with what they see, CONTAIN™ with what it understands. By using deep learning, it detects inclusion-type ores like tin, tungsten, nickel, copper and sulfides - helping miners unlock value previously lost in the tailings stream. Transform unknows into insights. Transform ore variability into opportunity. Transform buried value into measurable output. CONTAIN™ doesn't just sort - it thinks. it sees beyond the surface to detect what others can't, making your plant smarter, leaner, and more profitable.
