Moscow International Mineral Processing Congress (MIMPC-2025) brought together leading specialists in the field of solid mineral processing, researchers, equipment and reagent manufacturers to share their experience, discuss issues and possible solutions.
Institute TOMS took part in the international scientific symposium Miner’s Week 2025 held by MISIS University, February 3–7. The specialists of Mining audit and consulting department delivered a report on advanced approaches to create geometallurgical block models and assess process variability of ores.
Institute TOMS was assessed and passed as consistent with the criteria of the national accreditation system.
In December 2024, Institute TOMS jointly with specialists of Tufekcioglu company and Sever Minerals JSC successfully carried out trials of a new advanced lab-scale flotation cell with computer-aided process control – TK LabFroth by Tufekcioglu.
Institute TOMS acted as one of the key sponsors of the 20th MINEX Mining and Exploration Forum that took place in Moscow on 9-10 October, 2024. The event was held under the slogan “People. Technologies. Mineral Resources”

Derrick Screen Pilot-Scale Testing
In August 2020, Institute TOMS (Irkutsk) in partnership with Thrane Teknikk initiated testing of a fine screening technology using Derrick Stack Sizer 2SG 48-60R-1STK by Derrick Corporation (USA). The testing is run at screen aperture sizes starting from 45 µm.
The sizer installed in Institute’s TOMS lab corresponds fully to commercial units in terms of its characteristics, which allows fine screening parameters to be one-to-one scaled up. Moreover, high specific throughput of the screen and high efficiency of the resulting separation make it possible to conduct pilot-scale tests and produce sized products for any further process testworks.
Stack Sizer type screens are widely recognized in mining and processing industries and applied as classifying equipment within ore comminution and mid-products regrinding circuits as well as for preparation of the material to be fed to wet magnetic separation, flotation and other process operations.
