Batu pasir besi: Perbedaan antara revisi

'''Batu pasir besi''' ({{lang-en|Direct reduced iron}}, disingkat sebagai '''DRI'''), juga disebut '''tempaan''' atau '''besi spons''' atau '''besi busa''', adalah jenis [[batu]] [[besi]] yang dihasilkan langsung dari reduksi [[bijih besi]] (dalam bentuk batu benjolan, pelet) menjadi [[besi]] dengan mengurangi unsur [[karbon]] gas yang dihasilkan dari pembakaran [[gas alam]] atau [[batu bara]]. Banyak bijih cocok untuk reduksi langsung. Besi spons harus dipadatkan untuk diproses lebih lanjut atau dilebur, karena mengandung kotoran yang tidak diinginkan (terutama terak).<ref>{{cite web |url=http://www.businessdictionary.com/definition/direct-reduced-iron-DRI.html |title=What is direct reduced iron (DRI)? definition and meaning |publisher=Businessdictionary.com |access-date=2011-07-11 |archive-date=2018-01-04 |archive-url=https://web.archive.org/web/20180104205144/http://www.businessdictionary.com/definition/direct-reduced-iron-DRI.html |dead-url=yes }}</ref><ref>{{cite web|url=http://metallics.org.uk/dri/|title=Direct reduced iron (DRI)|publisher=International Iron Metallics Association}}</ref><ref>R.
