7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Primetals successfully established the Hybrid Flotation Technology, which differs from the standard pneumatic flotation cells, on the non-ferrous mining market. The growing demands for high grade pellet feed with low content of silica and sulfur also makes that technology very interesting for the use in iron ore beneficiation. Primetals conducted a laboratory campaign with the in-house...

The interaction of fine iron ore powders with water plays an important role in iron ore granulation, an important step in iron ore sintering, and is usually assessed based on the determination of wettability, or contact angle, of iron ore powders. Generally, iron ores which have a lower contact angle show more efficient granulation. The Washburn capillary rise (WCR) technique has been widely...

Oxidizing pelletization of imported high combined water bearing manganese ore fines was conducted by simulating grate-kiln process in electric tube furnace, and its consolidation mechanism was revealed by the determination of the mineralogy of fired pellet. The raw manganese ore fines were finely ground by HPRG for preparing pellet feed with specific surface areas of 2563 cm2/g and bentonite...
