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

This leaves a ,titanium, solid, which is removed by boring from the reactor and treated with ,water, and hydrochloric ,acid, to remove excess magnesium and magnesium chloride. The energy requirement is more as an 8-ton batch takes about four days.

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
