RECOVERY AND PURIFICATION OF TITANIUM OXIDE PIGMENT FROM ROSETTA ILMENITE MINERAL CONCENTRATE USING MODIFIED ORGANIC MATERIALS

Abstract

In recent decades, environmental issues have been highlighted due to their great importance. One of these issues is the optimal and practical use of plant and animal waste, which are among the most important atmosphere pollutants when incinerated. The preparation of new natural resins from these wastes has been studied, for example, by converting unused or plant pollutants such as cotton stalks, rice straw and wood residues into highly absorbent materials for unwanted metals (impurities). Cellulose is one of the most oldest chemical raw materials and, until now, has been the most crucial renewable resource of the chemical industry. The chemistry of cellulose has been vigorously promoted in recent decades. On the other hand, it is unfavorable for heavy metals working from aqueous solutions to be adsorbed across the hydrophobic porous carbon surface. Thus, the latter’s surface should be operational or modified. The procedures and the methodology of this study can be summarized in the following topics: - The first part: it involves synthesis of some new organic compounds as ion exchanger (different resins) derived from natural microcrystalline cellulose. The second part: it involved the study of several batches using synthes
