rise to diluted (25 %) sulfuric acid as a waste product (dilute acid), which can also contain heavy metals from the ore. Up until the late 1980s, most of these chemical loads (about 5 million tons per year in Europe) were dumped by freighters in open waters of the North Sea. As of 1989, an environmentally friendlier recycling-process was introduced

ore is dissolved in concentrated sulfuric acid solution (~ 85%) at a temperature of nearly 200 °C to prepare a titanyl sulfate solution. This solution is further purified and hydrolyzed to produce pure TiO2 [5]. In order to meet the demand for high-grade titanium ores, commercial practices including roasting and

In this research, a potentially more ecofriendly chemical pathway for TiO2 production from concentrated titanium ore, aka titania slag, is presented. The new method consists of three critical steps including transformation of the titania slag to a lower-valence titanium suboxide by aluminothermic reduction, digestion by using mild acid, and controlled hydrolysis accompanied by acid recycling.
