steel research international, EarlyView.H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Alkali roasting of bomar ilmenite: rare earths recovery and physico-chemical changes. [PDF]
, 2014 In this work, the alkali roasting of ilmenite (FeTiO3) is presented as a process route for integrated beneficiation of the mineral for rutile-rich phase and rare earth oxides; the latter is released as a consequence of physical changes in the ilmenite ...

Carbothermic Reduction of Zinc Ferrite by Microwave Heating
High Temperature Materials and Processes, 2013 The kinetics of carbothermic reduction of ZnFe2O4 in the temperature range 823–1223 K, was investigated in a microwave reactor. The mechanism of formation of ZnO and Fe3O4/FeO by decomposition of ZnFe2O4 was explained using the equilibrium calculations ...
