The HIsmelt Technology
THE HISMELT PROCESS IS SIMPLE
- Ore & coal are injected into the molten bath
- Hot blast is injected into the top-space to post-combust CO and H2
- Metal flows out continuously from the fore hearth
- Slag is batch tapped
Flexible and Sustainable in Raw Materials
Iron ore
- No blending or agglomeration necessary = No energy input
- Dry fines (-6mm) and slimes (ultra-fines) – used directly
- High phosphorus, alumina, titania or alkalis content feeds possible
- Can be pre-heated / pre-reduced to increase process efficiency
Steel plant wastes
- Recycle and reuse – less disposal
- Dry fine wastes and metallic fines – used directly
- E.g. mill-scale, steel-making slag, reverts, coke breeze
coal
- No blending, briquetting or coking required = No energy input
- Non-coking coals – ground to -3 mm and dried
- From coke breeze (low volatile) to high volatile thermal coal
