The granulated copper slag prepared by dry centrifugal granulation process was taken as oxygen carrier, a thermodynamic analysis and an experimental study were conducted for oxygen absorption and release reactions of copper slag. The effects of oxidation temperature, reduction temperature, particle size of copper slag and CaO addition on the phase composition of copper slag were investigated. The results show that the reactions of oxygen absorption and release of iron oxide in copper slag run step by step, and the granulated copper slag particles have certain capacity of oxygen absorption and release. Oxidation and reduction at higher temperature is beneficial to reactions of oxygen absorption and release of iron oxide in copper slag. Copper slag with smaller particle size is beneficial to the oxygen absorption reaction of FeO and Fe3O4, and addition of CaO is beneficial to the oxygen release reaction of copper slag.

以干法离心粒化的铜渣颗粒为氧载体,进行了铜渣吸氧和释氧反应的热力学分析和实验研究,考察了氧化温度、还原温度、铜渣粒径及CaO加入等对铜渣物相组成的影响。结果表明,铜渣中铁氧化物的释氧反应过程和吸氧反应过程都是逐级进行的;粒化后的铜渣颗粒均具备一定的吸氧和释氧能力;提高氧化和还原温度均有利于铜渣中铁氧化物释氧反应和吸氧反应的进行;铜渣粒径越小,越利于FeO及Fe3O4吸氧反应的进行;加入CaO有利于铜渣释氧反应的进行。

以干法离心粒化的铜渣颗粒为氧载体,进行了铜渣吸氧和释氧反应的热力学分析和实验研究,考察了氧化温度、还原温度、铜渣粒径及CaO加入等对铜渣物相组成的影响。结果表明,铜渣中铁氧化物的释氧反应过程和吸氧反应过程都是逐级进行的;粒化后的铜渣颗粒均具备一定的吸氧和释氧能力;提高氧化和还原温度均有利于铜渣中铁氧化物释氧反应和吸氧反应的进行;铜渣粒径越小,越利于FeO及Fe3O4吸氧反应的进行;加入CaO有利于铜渣释氧反应的进行。

The granulated copper slag prepared by dry centrifugal granulation process was taken as oxygen carrier, a thermodynamic analysis and an experimental study were conducted for oxygen absorption and release reactions of copper slag. The effects of oxidation temperature, reduction temperature, particle size of copper slag and CaO addition on the phase composition of copper slag were investigated. The results show that the reactions of oxygen absorption and release of iron oxide in copper slag run step by step, and the granulated copper slag particles have certain capacity of oxygen absorption and release. Oxidation and reduction at higher temperature is beneficial to reactions of oxygen absorption and release of iron oxide in copper slag. Copper slag with smaller particle size is beneficial to the oxygen absorption reaction of FeO and Fe3O4, and addition of CaO is beneficial to the oxygen release reaction of copper slag.
