JORDAN, P. Evaluation of reductants used for ilmenite smelting based on CO2 reactivity (Boudouard reaction) measurement. J. S. Afr. Inst. Min. Metall. [online]. 2011, vol.111, n.6, pp.385-392. ISSN 2411-9717.

SYNOPSIS The practice of ilmenite smelting in electric arc furnaces has been researched and published over the last few decades. An issue that has not been addressed is the understanding of the properties of ilmenite smelting reductants, and linking these properties to the subsequent smelting behaviour in the furnace. The reduction mechanism of ilmenite smelting is not fully understood, but it is believed that the Boudouard reaction plays a role. This paper investigates the behaviour of a number of reductants when reacted with CO2 at different temperatures.

Palavras-chave : Boudouard reaction; carbon reactivity; reductants; ilmenite smelting.
