Kinetic reduction of mill scale via hydrogen
Mill scale is very attractive industrial waste since it is rich in iron
(about = 72 % Fe) and it is suiTab. for direct recycling to the blast furnace
via sintering plant. In this paper the characterizations of raw materials
were studied by different methods of analyses. The produced briquettes were
reduced with different amounts of hydrogen at varying temperatures, and the
reduction kinetics was determined. Two models were applied and the energy of
activation was calculated
Kinetics of reaction of roasting of soda ash and ilmenite ore concentrate for formation of sodium titanates
Kinetics of reaction of roasting of soda ash and ilmenite ore concentrate for formation of sodium titanates
Alkaline metals and hydrogen titanates are of great interest for possible
applications. The soda ash and Rosetta ilmenite ore concentrate briquette
were investigated. The kinetic of formation of sodium titanate was studied in
the temperature range 700°C to 900°C
