The starting product to produce pig iron is iron ore. Iron ore is transformed into pig iron through oxidation. Iron ore is transformed into pig iron through reduction. Iron ore does not exist in its pure form in nature but in a chemical compound. It is not necessary to pre-process the iron. Rough pieces of iron must be broken up to fit into the blast furnace. Breaking up rough pieces of ore is the only way to pre-process ores. Blasting is a thermal pre-processing to eliminate unwanted elements. The most important iron ore is red iron ore. The most important iron ore is magnetic iron ore.

Draw lines. limestone coke ore This material is added in pre-processed pieces. This material is added together with dolomite in order to liquefy the earthy elements that don’t melt easily and the fuel ash into slag. Heat and carbon (C) are necessary to produce pig iron in the blast furnace. This material provides both. It has a high caloric value. It is also important for the reduction of oxygen. 05 A2–B1 ✗ ✗ ✗ ✗ ✗ ✗ 06 A2–B1 listening 9i6ik7 07 A2–B1 limestone ore coke Word bank carbon Kohlenstoff caloric value Heizwert oxygen Sauerstoff coke Koks limestone Kalkstein dolomite Dolomit liquefy verflüssigen fuel ash Brennstoffasche slag Schlacke 90 Unit 17 Nur zu Prüfzwecken – Eigentum des Verlags öbv
