In 2017, CCI LLC implemented the whole range of laboratory tests to determine the metallurgical properties of iron ore materials including:
- determination of iron ore reducibility by the reducibility rate index according to DSTU ISO 4695;
- determination of the free swelling index of iron ore pellets for blast furnace raw materials in accordance with DSTU ISO 4698;
- determination of reducibility by the index of the final degree of reducibility in accordance with DSTU ISO 7215;
- dynamic fracture tests during the reducibility process at low temperatures according to DSTU ISO 13930;
- determination of the relative reducibility according to ISO 7992.
CCI The testing laboratory performs the following tests:
- grain size analysis;
- compressive strength;
- actual, bulk, temped density and porosity;
- mass loss during ignition;
- mass fraction of moisture, hygroscopic moisture;
- mass fraction of total, metallic iron, iron oxide, ferrous iron;
- mass fraction of total manganese, manganese dioxide;
- mass fraction of chromium, chromium oxide (III);
- mass fraction of total carbon;
- mass fraction of sulfur;
- mass fraction of sodium and potassium oxides;
- oxides of calcium and magnesium, oxides of silicon, aluminum, barium;
- mass fraction of phosphorus, vanadium, nickel, copper, lead, titanium, cobalt and other elements.
