“…From this figure, we can see the reaction rates are increased due to the increase of acid concentration from 1, 2, and 3 M. The result was similar to that reported in Jia and Li [1,15]. A. Mehdilo et.al had reported that acid concentration and treatment time of sulphate process were effecting the growth of TiO 2 [16]. According to W. Zhang et al the ilmenite, leucoxene and rutile contains about 40-65%, more than 65% and 95% TiO 2 respectively [17].…”

The present study is to clarify the present influences of acid concentration and temperature of caustic hydrothermal method on extracting the titanium dioxide (TiO2) from synthetic rutile waste. In this experimental work, the caustic hydrothermal method comprises two processes: a decomposition and the sulphate process. The extracted titanium is characterized by using a electron dispersive X-ray spectroscopy to specify its chemical composition, field emission scanning electron microscope to determine the morphology and particle size, and lastly it is the X-ray diffraction to analyse the crystallinity of extracted titanium. In this study, we found that both acid concentration and temperature affected the TiO2 growth while the calcination process could improve the crystallinity of extracted titanium.

“…Recently, several new methods of concentration of zinc oxide ores have been proposed: sulfidizing roasting in the atmosphere of superheated water vapor in the presence of a pyrite concentrate (Gulyashinov et al, 2003); depressing of limestone and dolomite with citric acid, and silicates and iron oxides with liquid glass and caustic soda when flotation of ordinary smithsonite ores with extraction of 83.6% Zn into a concentrate containing 43.5% zinc (Algebraistova and Kondrat'yeva, 2009); depressing a rich zinc ore with sodium fluoride and dextrin using cationic and cationic-ion collectors (KAX-Armac with a ratio of 2:1) (Mehdilo et al,2013). However, despite the obvious success of flotation enrichment of oxide ores, known and new methods are associated with the inevitable formation of tailings.…”

Red mud (RM) is an industrial waste produced in large amounts during alumina extraction from bauxite. Its disposal generates serious environmental pollution due to high alkalinity. Therefore, a strategy for the effective utilization of RM must be developed. For instance, RM may be transformed into useful products, such as adsorbents. Given its high concentrations of aluminum oxides, iron oxides, titanium oxides, silica oxides, and hydroxides, RM may be developed as a cheap adsorbent for the removal of various ions from aqueous solution and soils (e.g., metal and non-metal ions, phenolic compounds, and dyes) and waste gas purification (sulfide and carbide). This review summarizes the background, properties, and applications of RM as an adsorbent. Proper approaches of removing metal and non-metal elements from wastewater are also systematically reviewed and compared. Emphasis is placed on the surface modification of RM to obtain high adsorption. Finally, the scope for future research in this area for RM is discussed in depth.
