Abstract: <br /> <br /> <br /> <br /> <br /> <br /> <br /> Iron ore crisis for supplying iron and steel industry occurs in Indonesia. On the other <br /> <br /> <br /> <br /> <br /> <br /> <br /> hand, raw materials for these industries depend on foreign supply. Lateritic ore is <br /> <br /> <br /> <br /> <br /> <br /> <br /> abundance in Indonesia. But, this material has been used as nickel source. It is known <br /> <br /> <br /> <br /> <br /> <br /> <br /> that lateritic ore has a complex characteristic due to the presence of clay minerals and <br /> <br /> <br /> <br /> <br /> <br /> <br /> crystal water. <br /> <br /> <br /> <br /> <br /> <br /> <br /> This research is conducted to enhance iron content from lateritic iron ore taken from <br /> <br /> <br /> <br /> <br /> <br /> <br /> Bukit Besi, Kalimantan, via the reduction of impurities minerals, i.e. Al2O3 and SiO2. The <br /> <br /> <br /> <br /> <br /> <br /> <br /> method used is reverse cationic flotation by using amine collector. Optimum flotation <br /> <br /> <br /> <br /> <br /> <br /> <br /> process condition determination is conducted through variation on: pH pulp, feed fraction <br /> <br /> <br /> <br /> <br /> <br /> <br /> size, solid percentage, and collector dosage. <br /> <br /> <br /> <br /> <br /> <br /> <br /> The result shows that Fe content achieved is 10,47%, while SiO2 and Al2O3 removal <br /> <br /> <br /> <br /> <br /> <br /> <br /> achieved is 5,57% and 8,57%.
