.A substitute for fine coal in copper smelting by CDQ dust

摘要

The present invention occurs in the coke cooling by-product during conventional manufacturing does not easily, be made to solve the closed end is expensive fine coal having, it steelworks coke as a fuel to be used during the continuous copper smelting process for instead of the pulverized coal manufacturing process, and the conventional of pulverized coal and the chemical composition is substantially the same, while the effect is intended to use the coke cooling excellent dust.
