In October 2025, Institute TOMS in cooperation with FINGRI company successfully commissioned a pilot vertical mill for fine grinding testworks.
Institute TOMS acted as a silver sponsor of the 21st MINEX Mining and Exploration Forum that took place in Moscow on 8-9 October, 2025.
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.

Pilot testing facilities
- Pilot testing of ores using various process flowsheets (gravity separation, gravity separation – flotation, gravity separation – leaching, gravity separation – flotation – leaching)
- Flexible process flowsheet of a pilot plant capable to treat continuously up to 3–5 tonnes of ores (the plant's throughput 20–100 kg/h)
- A set of tests to study physical-mechanical and process properties of ores allowing deposits mapping to be performed, an efficient process flowsheet to be advised, and recommendations for process design criteria and feasibility study to be provided.
