Perolehan Tio2 Dari Iron Ore Mengandung Titanium Melalui Proses Reduksi Karbon Dan Pelarutan Asam

Abstract

<span>REDUCTION AND LEACHING PROCESSES<span><strong>. </strong><span>Indonesia has a large source of iron ore <span>which is quite tempting for the purposes of exploitation in form of raw materials as well as <span>for the production of pig iron. However, not all sources of iron ore are proved useful since <span>not only because the present of deposit is scattere dinamounts of less significant but also <span>because it contains element of tin oxide compounds with iron like ilmenite or FeTiO<span>3<span>. <span>However,ilmenite can actually be used as a source of titanium metal which is much more <span>valuable than Fe it self. In order to recover the Ti from their respective compound it is <span>required the release of strong bonds between the atoms in the compound. This paper reports <span>the recovery of Ti oxide of ilmenite containing iron ore which was obtained through a <span>combination of carbon reduction and acid leaching processes. Carbon reduction of iron ore <span>was carried out through mechanical milling between iron ore and carbon with a ratio of 1:1. <span>This was successively followed by a sintering at a temperature of 1000 <span>o<span>C employing a <span>heating rate of 10 ° C/min for 0-3 hours. The reduction process has resulted in the <span>formation of 27.83wt% TiO2. In order to improve the recovery level of TiO<span>2<span>, further <span>reduction process was conducted through an HCl leaching. This successive stage produced <span>fine powders in the form of deposits. Based on our quantitative analysis, the recovery of <span>TiO<span>2 <span>increased to a level of 73.73%.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /></span></span></span></span></span></span></span></span></span></span></span>
