Rosgeo started the final manganese ore exploration stage in the Kozinskaya area of the Krasnoyarsk Region

AO Sibirskoye proizvodstvenno-geologicheskoye objedinenije (city of Krasnoyarsk, the company is a part of Rosgeo state parent company) commenced the final stage of oxide manganese ore exploration in the Kozinskaya manganese area.

The company performs the exploration under the state contract signed in summer 2017 between the parent company and the customer, the Department for Subsoil Use, in the Central Siberian Region. The project will be completed by the end of 2019.

The area is located in Kuraginsky and Turukhansky Regions of the Krasnoyarsk Region. Geologists’ priority is to perform the technological study of the possibilities to process ore by heap leaching.

In 2018, a set of geophysical and mining drilling operations was conducted in the area.

When the profile electrical prospecting materials were confirmed in the wells, it was found out that the disruption zone in the carbonate-argillaceous area was 40-50 meters deep and was characterized by an extensive karst development as well as by crumbling and mudded rock areas.

The technological study of the possibilities to process oxide manganese ores by heap leaching was continued using the material of laboratory and technological samples taken from the Kozinsky mineralization and Karaulnaya Gorka site. Experimental works for using the technology for the UTP-1 consolidated technological sample of 15 tons was performed. Its chemical and mineral composition was specified and the ore was prepared for further agglomeration and putting into the percolation column. Experimental laboratory work was continued with small samples (10-50 kg) in the columns with a diameter of 0.1-0.25 m and height of 1-5 m.

Various modes of technological processes of electrolysis obtained from purified electrolyte were elaborated and test batches of electrolytic metal and manganese dioxide were received.
