Recovery is a process by which deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations, are introduced by plastic deformation of the material and act to increase the yield strength of a material. Since recovery reduces the dislocation density the process is normallypanied

Conversion Iron and carbon rich fines, dust and wet sludge converted to high quality feedstock. Mixing Connects fine carbon particles to iron oxides for improved reduction. Binder Less binder for more high value metallics and

The present paper describes a process where in two subsequent steps by the use of a Top Blown Rotary Converter technology a simultaneous recovery of zinc, iron and other valuable metals should be possible. Investigations which were done in an advanced technical scale gave satisfying results.

Once the iron oreesite, it is much easier to beneficiate pelletise it. The efficiency of iron recovery is 90 95 as against 70 75 in the conventional beneficiation plants the left over Fe in the tailings is only 10 15 as against 35 45 in
