[ABSTRAK Limbah Industri baja mill scale sudah berhasil diolah menjadi pigmen besi oksidawarna kuning dan merah. Hasil pigmen besi oksida melalui variasi pH (4,7 dan 11)pengendapan menghasilkan fasa berupa goethit α-FeOOH, lepidokrosit γ-FeOOHdan magnetit Fe3O4. Pengaruh peningkatan pH saat pengendapan maka menurunkanterbentuknya fasa besi hidrat dan terbentuknya fasa besi oksida. Sedangkan pigmenmerah hematit Fe2O3 diperoleh setelah proses kalsinasi 900oC selama 2 jampenahanan. Disimpulkan bahwa hasil sintesa mill scale menjadi pigmen kuningterbaik terjadi pada pH-4 dan pigmen merah terbentuk pada calsinasi CpH-11,kondisi ini yang paling mendekati produk pigmen komersil. Perlu penguasaanteknologi milling untuk mencapai standard ukuran partikel pigmen komersil. ABSTRACT Industry Steel Waste (Mill Scale) have processed successfully into yellow and rediron oxide by precipitate method. Variation pH (4, 7, and 11) in the precipitatemethod resulted Goethite (α-FeOOH), Lepidocrosite (γ-FeOOH), and Magnetite(Fe3O4) phase. Increasing pH value in the precipitate method show decreasingfraction iron hydrate's phase and growing iron oxide's phase. Red oxide wasprocessed by calcination temperature until 900oC for 2 hour. As conclution of thisresearch is yellow oxide synthetic pigment occur in pH value 4 and red oxidesynthetic pigment occur in pH value 11. This condition shown like identic with ironoxide commercial pigment. Fine milling will be needed to reach particle sizecommercial pigment standard.;Industry Steel Waste (Mill Scale) have processed successfully into yellow and rediron oxide by precipitate method.
