A group of geologists, enrichment technologists and occupational safety and health specialists from Russia, Kazakhstan and Ukraine attended an intensive training seminar with technical visits to Helsinki and Talvivaara.
At the Terrafame open-cast polymetallic mine (formerly Talvivaara), the delegation studied the organization of mining operations and examined the heap bioleaching zone, where the gold extraction process takes place, even in severe frosts, at a temperature of 40-60C due to the exothermic reaction in the heap. The technological scheme and equipment of the crushing line was disclosed in detail in the reports of Sandvik and Outotec specialists.
The delegates for the geological section from MMC Norilsk Nickel, Norilskgeology and AGD Diamonds examined issues of quality control of geological exploration and core samples (speaker Dr. Julia Cherepanova), studied the On-Line Mine technology of the Finnish company IMA Engineering – collection and analysis in real time data on the metal content during production activities from core, drilling waste and from ore on a conveyor belt and visited the Finland Geological Survey GTK, founded in 1885 by decree of Emperor Alexander III.
