Recovery of solid materials that go along with furnace gases into atmosphere, economically and environmentally are very important. Flash furnaces of copper production due to the its procedure nature of production, produced Significant amounts of dust. For example, in Khatoon Abad copper plant, produce annually 6,000 tons of dust containing 1500 tons of copper. In this research, converting of produced dust in Khatoon Abad into portable product (briquettes, pellets) and charging to copper convertor has been examined. The results of experiments showed that magnetic separation of magnetite in the dust is not feasible by using common machines and also is not economic. But to reduce destructive effect of magnetite, dust can be mixed with copper concentrate. briquettes produced by water-based adhesives such as cement and sodium silicate causing the dust to be hydrated. Thus, the briquettes collapse when charged to the converter. On the other hand, briquettes produced by mixing coal tar pitch and beet molasses (with less than 0.5% of ammonium nitrate as an additives) have the best result in terms of briquette strength. Compressive strength of produced briquettes with 12% beet molasses and 3% coal tar pitch is about 20 MPa and brazilian strength of 8.1 MPa was obtained. Also examination of the solubility of the sample inside molten matte indicated that the briquette completely has been solved.
