use of plastics in iron ore sintering

Iron processing Ores |

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a travelinggrate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then .

FACT SHEET Steel industry coproducts

Iron orebased steelmaking accounts for about 70% of world steel production. Iron ore is reduced to iron and then converted to steel. The main inputs are iron ore, coal, limestone and recycled (scrap) steel. The main orebased production routes are: ironmaking via the blast furnace (BF) followed by steelmaking in the basic oxygen
