Methods of Extracting TiO2 and Other Related

Although ilmenite and rutile are extensively used to extract TiO2 at the industrial level, through the sulphate and chloride processes, they can also be recognized to possess the potential to be employed as TiO2, the sulphate process and chloride process are the two common methods utilized for extracting TiO2 from ilmenite and rutile, respectively. 2.1. Sulphate Process Statistical data reveal that 98% of manufacturers in China use the sulphate process for the production of TiO2 [33]. The process can be categorized into four main stages, Methods of Extracting TiO2 MDPI

The characterization and H 2 SO 4 leaching behavior of a Nigerian ilmenite ore following mechanical activation and alkali roasting were investigated. The effects of NaOH/ore ratio, H 2 SO 4 concentration, leaching and roasting temperature on the Ti recovery from the milled ore were examined. The results show that mechanical activation The process of ilmenite alteration is known as Thailand, Nigeria, Myanmar, and China.

Towards sustainable TiO2 production: An investigation of environmental

This paper presents life-cycle environmental impacts and health hazards of the ilmenite and rutile processing routes which are very little explored despite a significant quantity of production worldwide. The study is carried out through a life-cycle environmental-impact assessment of the ilmenite and rutile mining production processes in Australia, To facilitate that process, effective measures should be taken to make the mining extraction processes sustainable (Awuah-Offei and Adekpedjou 2011; Law and Lane, 1991; Mudd, 2009; Navarro and Zhao, 2014; Norgate et al., 2007).
