Steinert to sponsor Comminution '25 and Physical Separation '26

I think everyone in the mining industry is now well aware of how important sensor-based electronic sorting has become and MEI is pleased to have the continuing involvement of Steinert, one of the leaders in this field. Steinert sponsored two of last year's 4 MEI conferences, Physical Separation '24 and Critical Minerals '24.

It is not surprising that Steinert is to sponsor Comminution '25, as sorting waste rock and ore with low concentrations prior to comminution saves energy and water and enriches the grade of the ore.

Steinert's ‘dual energy’ x-ray transmission (XRT) is ideally suited for ore sorting because the x-ray radiation can penetrate stones with particle sizes up to 100 mm, allowing metals to be detected, even when they are not on the surface. 

In addition to XRT, Steinert offers other sensors that can be combined with one another. XRF (x-ray fluorescence) can be used to determine and sort individual chemical elements very precisely and optical sorting and lasers are well suited to the detection of ores with different colours, or crystalline structures.

Steinert is also the first sponsor to sign up for Physical Separation '26. There are many applications of Steinert technology in physical separation.  Electronic sorting has long been used in the recovery of diamonds, X-ray sorting systems screening out diamonds accurately and with high throughput rates at an early stage in the process. In contrast to conventional x-ray luminance processes, Steinert diamond sorting machines use high-resolution x-ray transmission sensors that screen the rock throughout. Detection takes place at the atomic level, and surface impurities do not affect the detection. This solution can be used early in the process in order to remove large diamonds before they are damaged or broken up in the subsequent crusher stages. Near-infrared (NIR) technology is also being used to analyse the complete material stream and reliably separate kimberlite from waste rock. Modern sorters have great advantages over the conventional sink/float process, not only in diamond processing.

We look forward to hearing the latest developments in electronic sorting at Comminution '25 and Physical Separation '26.
