Abstract

Commercial titanium dioxide is a fine powder with a purity of 97% for the rutile grade and 98% for the anatase grade. This product serves as the primary white pigment widely used in the paint, coating, plastic, paper, and cosmetic industries, as well as for solar cells. Currently, 80-90% of the titanium dioxide demand in Indonesia is still imported. Therefore, the establishment of this plant aims to meet domestic demand while increasing the added value of ilmenite, a byproduct of local tin mining. This plant utilizes the sulfate process by reacting the raw materials ilmenite (FeTiO3) and sulfuric acid (H2SO4). This exothermic reaction is carried out in a three-stage reactor system at temperatures of 150°C, 100°C, and 70°C, which is capable of achieving a conversion and yield of 93-96%. Subsequently, the product undergoes filtration, crystallization, and hydrolysis stages at 90°C (1 atm). The process concludes with a calcination stage at 800°C to form rutile crystals, which are then cooled and stored. The plant is designed with a production capacity of 60,000 tons/year. It will occupy a 37,150 m2 land area in the Sadai Industrial Estate (KIS), Tukak Sadai District, South Bangka Regency, Bangka Belitung Islands. The economic evaluation is summarized as follows: • Total Capital Investment (TCI): Rp1,769,948,797,799.05 • Total Production Cost (TPC): Rp2,571,791,830,394.41 • Return of Investment (Before Tax): 27.8% • Return of Investment (After Tax): 20.9% • Internal Rate of Return (IRR): 15.82% • Pay Back Period (PBP): 3 years and 9.5 months • Break Even Point (BEP): 39.24%
