Study of Technology about Recovering Iron, Carbon from Zinc Volatile Kiln Slag

Abstract:

Article Preview

The iron, residue valuable metal in the zinc-volatile kiln slag, has its own characteristics of complex mode of occurrence, the relative high content and difficult recovery. Based on the differences in magnetism and specific gravity between iron rich part and carbon rich part, integrated to the water waste problem through current dry process to recover iron, ribbon, a complete set of all dry beneficiation process had been developed. It included: microwave drying, coarse crush---pre-screening technology, mid crush---fine crush technology, two parts---three steps magnetic separation to produce Fe powder, four steps magnetic separation and air medium re-election of carbon powder processing steps. Meanwhile, it carried out a reasonable selection for the crush equipment and gravity separation equipment. And it developed a new type of magnetic separation equipment. They enable a more uniform particle size and a higher grade and recovery of Fe and carbon powder, as well as lower energy consumption and higher production efficiency advantages. The zinc-volatile kiln slag is promoted to be a further recycling, finally.
