Contact SupplierDolochar is a by-product generated during the production of sponge iron (Direct Reduced Iron, or DRI) in rotary kilns using dolomite and coal as feed materials.
Key Points about Dolochar:
Composition:
It contains unreacted coal (char), dolomite ash, iron oxide, and other inert materials.
Generation:
It is produced when coal and dolomite are used together in the reduction of iron ore in sponge iron kilns. The non-metallic part that doesn’t participate in the reduction process is expelled as dolochar.
Appearance:
It looks like a dark, granular or powdery substance.
Uses:
Fuel: Can be reused in captive power plants as a low-grade fuel.
Brick manufacturing: Used in the fly ash brick industry.
Land filling or road base material, though this depends on local environmental regulations.
Environmental Concerns:
It must be handled carefully, as improper disposal can lead to land and water pollution.
