| Abstract | Result of the Study : 1. The result on chemical analysis shows that the head ore contains 5.38% TiO₂ and 18.45%Fe, respectively. Based on the result of mineralogical analysis, the head ore consists of ilmenite, magnetite, hematite, and gangue minerals such as hornblend, amphibole, quartz, kaolin, and etc.. Especially, most of ilmenite is finely disseminated by gangue minerals. This may cause very poor liberation in the separation process. 2. The results on tests of crushing and screening show that the ilmenite particles are mainly distributed in intermediate fractions while the particles of gangue minerals such as feldspar, hornblend, kaolin are distributed in fine fractions. In fact, the ilmenite particles are not concentrated in certain fractions. This is due to the poor liberation of ilmenite particle from the other minerals. 3. For the gravity separation, shaking table concentrator was used. Optimum operating conditions are 11 ℓ/min water feed rate, 250g/min, ore feed rate and particle size of feed having 65mesh. The result shows that ilmenite concentrate containing 44.20% TiO₂is obtained with 39.35% recovery. The result on microscopic analysis of the ilmenite concentrate shows that it still consists of garnet, magnetite and chlorite, which are on similar range of specific gravity. So, the ilmentie concentrate should be further treated in order to get higher grade of more than 50% TiO₂. If the ilmenite concentrate includes Middling 2 product, the ilmenite concentrate having 19.76% TiO₂ and 40.90% Fe₂O₃ is recovered with 75.88% recovery, at 35mesh grinding. The grade of the ilmenite concentrate is too enough for the use of protecting the erosion of hearth refractories. .... |
