Chemistry and Mineralogy of Titanium-rich Slags

2021-3-20 · Close examination of Table 1 shows clearly that using common halogenated heavy liquids such as bromoform (2860kg m 3), 1,1,2,2- tetrabromoethane (2960kg m 3) or even the denser diiodomethane (3125kg m 3) only allows us to separate the titanates, oxides, and sul- phides phases from minor silicates minerals from the gangue.

Titania recovery from low-grade titanoferrous minerals ...

2011-10-1 · 1. Introduction. Titania (TiO 2) is a white pigment used in paints, paper, plastics, cosmetics and coatings.Its wide application is due to its higher opacity and covering power. There are two commercial methods of TiO 2 production, the chloride and the sulphate process. In the chloride process titanium mineral is converted into TiCl 4 which is subsequently oxidized at high temperatures.

Formation of K–Cr Titanates from Reactions of Chromite

2020-4-24 · However, the formation of these phases does not proceed directly on chromite, but requires additional titanium source. The relationship between titanates is found to be a function of the activity of the potassium component in the fluid/melt. Priderite is an indicator of the highest potassium activity in the mineral-forming medium.
