As shown, three distinct zones with their own characteristics are clearly observed: the Zone I is a mass gain during a period of 50 seconds, which represents the initial stage of the ilmenite chlorination, and probably corresponds to the liquid FeCI2 and MnCh formation, as discussed in detail below,The U.S. Department of Energy's Office of Scientific and Technical Information
An exclusively surface reaction was observed at 500-800 K, resulting in the consumption of chlorine and the formation of oxygen, which was detected by a gas chromatography-coupled pulse reactor,This series of experiments shows that (i) dissolved aluminum interacts with sapphire-c, (ii) that the IEP can be decreased by solution replacement (in our interpretation a significant part of the adsorbed aluminum can be desorbed), and (iii) that some aluminum has an irreversible influence on the zeta-potential.

In this paper, the kinetics chlorination of β-spodumene for the extraction of lithium has been studied using gaseous chlorine as chlorinating agent. The effect of chlorine flow rate, temperature, mass of the sample, and partial pressure of Cl 2 was investigated. The study of the effect of chlorine flow rate indicated that the chlorination of β-spodumene may be carried out in the presence of active chlorinating species The chlorine partial pressure was found to have an appreciable effect on ,High temperature chlorination of titanium bearing minerals: part IV.
