An official ceremony marking the commissioning of a concentrate beneficiation facility

An official ceremony marking the commissioning of a concentrate beneficiation facility took place on the 17th of November 2022 at the Andrey Varichev Mikhailovsky GOK (Metalloinvest). Construction of the new beneficiation facility was fulfilled based on the process design criteria and engineering design developed by Institute TOMS.

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, zink 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.
