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”
This year TOMS team has crossed the world’s deepest lake Baikal on a swift-sailing yacht
TOMS specialists have visited the construction site of the copper plant MOF-3 of Almalyk Mining and Metallurgical Complex (Uzbekistan). The construction has been implemented within an investment project “Development of Yoshlik I deposit”. The deposit is rich in such valuable metals as gold, copper, silver, and molybdenum
Institute TOMS took part in an annual contest “Russian Mining Award” which is informally called “Mining Oscar”. The contest is aimed at an independent evaluation and promotion of the best achievements in various fields of mining and processing industry.
In October 2023, Institute TOMS participated in the 19th Mining Forum MINEX Russia 2023 held in Moscow
Metallurgy
Institute TOMS carries out metallurgical testworks on different types of ore and processing products containing nonferrous metals (Au, Ag, Pt, Zn, Cu, Pb, Mo, Co, Nb, Ni etc.)
The metallurgical laboratory of Institute TOMS is fully equipped and uses advanced methods that allow performance of the following works:
- Leaching tests in standard conditions (bottle tests, etc.);
- Intensive cyanidation tests on gold-containing products in ACACIA reactor;
- Tests to identify CIP process parameters (sorption isotherm, sorbent type, tanks etc.);
- Modeling of CIP (RIP) and CIL (RIL) processes, Pump Cell;
- Intensive leaching tests of Au, Ag concentrates under the influence of temperature and using special reagents;
- Heap leaching (physical and mechanical characteristics of ore and ore pellets, leaching under agitation conditions, in a percolator and in columns of 6 meters high);
- Copper, zinc and other metals recovery from productive solutions (EW, SX-EW);
- Autoclave oxidation of any mineral products: gold containing ores and concentrates, sulphides, aluminum bearing products, zinc fumes etc. (POX);
- Testing by means of modern hydrometallurgical processing technology of refractory concentrates: ultrafine grinding and oxidation in special reactors without temperature and pressure – ore preparation for leaching, separation of refractory sulphides (Au, Ag, Cu, As, Fe ores). Research is carried out using automated pilot plant (Leachox);
- Hydrometallurgical and pyrometallurgical tests for any type of ore;
- Tests for metallurgical products and processing tails detoxification (cyanide destruction, arsenic detoxification etc.);
- Development of flowsheets for metallurgical treatment as well as recommendations for Design Criteria;
- Pyrometallurgical treatment of precious metal concentrates;
- Precious metals refining;
- Albion Process Testwork in a special unit by Glencore Technology Pty Ltd (Au, Zn, Cu, hydrometallurgical technology is an alternative to pyrometallurgical processes, autoclave and bacterial oxidation).
Institute TOMS offers new technologies in the following sphere:
- Cyanide containing flows detoxification, cyanide regeneration and non-ferrous metal recovery from solution;
- Detoxification and disposal of arsenic bearing products;
- Detoxification and disposal of mercury bearing waste;
- MMS Cyanide Destruction Process CN-D.
Institute TOMS suggested a way for copper sulphide products processing based on a combination of hydrometallurgical and flotation technologies. This technique not only helps to increase copper recovery into a final product but also to significantly decrease the amount of concentrate (up to 3 times) that is subsequently fed to autoclave decomposition or even to completely eliminate this section.
