The effect of roasting temperature at 400 C and sulphuric acid consentration on TiO2 extraction process from zircon sand Ilmenite

---

In this research, roasting temperature 400 ? and sulphuric acid concentration variations was conducted to obatain titanium dioxide from zircon sand. The research was done through extraction metallurgy method which involved physical, chemical and mechanical treatments. Zircon was magnetically separated, mixed with NaOH, and roasted with temperature of 400 ?. Characterization with XRD of the sample before and after magnetic separation was conducted. Peaks obtained from NaFeO2, NaTiO2, Na0.75Fe0.75Ti0.25O2 and TiO2 compounds were observed. In tis study, leaching process lastd in two stages. For the first leaching samples of combustion products are leached using distilled water to remove water-soluble impurities. For the second stages, the deposition obtained from stage one is leached using 8, 10 and 12 M concentrated sulphuric acid at high temperature to dissolve iron. XRD was used to characterize TiO2. The resulut showed that the sample at temperature of 400 ? and consentrated sulphuric acid of 12 M is whiter in colour compared to other samples. Furthermore 400 ? and consentrated sulphuric acid of 12 M, the titanium dioxide produced is 32,3% and 11,5% for rutile and anatase, respectively.
