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.
Comminution
Physical and mechanical properties, parameters of crushing, grinding and abrasion
- Uniaxial compression and extension strength of rocks
- Point load strength index by Point Load Test (PLT)
- Bond Impact Crushing Work Index Test (CWi)
- Bond Rod Mill Work Index Test (RWi)
- Bond Ball Mill Work Index Test (BWi)
- Bond Abrasion Index Test (Ai)
- Parameters of autogenous and semi-autogenous grinding using Starkey method – SAGDesign Test (SDT), SAG Variability Test (SVT)
- Parameters of breakage by drop-weight using a method by JKTech Pty Ltd – Drop Weight Test (DWT)
- Parameters of breakage by drop-weight using a method by SMC Testing Pty Ltd – SMC Test (SMC)
Parameters of fine grinding and screening
- Fine screening parameters using Derrick method
- Fine screening parameters using Kroosh method
- Parameters of fine grinding in a tower ball mill using a method by Metso:Outotec – JarMill Test (Vertimill or analogous)
- Parameters of ultrafine grinding in a vertical stirred mill using a method by Metso:Outotec – HIG Mill Test
- Parameters of ultrafine grinding in a vertical stirred mill using a method by FLSmidth – VXP Test
- Parameters of ultrafine grinding in a horizontal stirred mill using a method by Glencore Technology – IsaMill Test
Pilot HPGR testing, simulation of comminution circuits
- Pilot equipment for sample preparation
- Fine crushing parameters using a method by Köppern – HPGR Pilot Test
- Circuits simulation using software packages: JKSimMet, Bruno, UsimPac, Molycop
Results from lab-scale and pilot testworks are used for comminution circuits design of greenfield plants (process design criteria, basic design, feasibility study) as well as for optimization of crushing and grinding equipment performances at existing operations.
