摘 要: 在1 873 K條件下對(duì)銅在富FeO熔渣中的氧化溶解行為進(jìn)行了研究。 結(jié)果表明： 銅氧化物在富FeO熔渣中以Cu2O的形式存在； 熔渣中CaO的含量將對(duì)銅的氧化溶解產(chǎn)生影響， 隨著渣中CaO含量的增加， 熔渣中的銅含量逐漸下降， 但在不同溫度下， 這種影響的作用各不相同； 當(dāng)溫度較高時(shí)， 渣中CaO含量對(duì)銅的氧化溶解影響較大， 且隨著溫度的降低， 其影響作用明顯變緩； 反應(yīng)體系的氧分壓對(duì)銅的氧化溶解影響較大， 在熔渣中γ(CuO0.5)不變的情況下， 銅氧化物的溶解與體系氧分壓的四分之一次方之間呈正線性關(guān)系。

Abstract: The oxidation dissolution behavior of copper in the FeO-rich slag at 1873 K was investigated. The results show that the copper oxidate is Cu2O. The CaO content in slag has influence on the copper oxidation dissolution in the FeO-rich slag. The copper content in slag decreases gradually with the increase of CaO content in the slag. But the influence is different under different temperatures. The influence of CaO content on the copper content in slag at higher temperature is relative obvious and becomes plain at lower temperature. The partial oxygen pressure of reaction system has great influence on the copper oxidation dissolution in the FeO-rich slag. The curve of copper oxidation dissolution in slag and the quarter root of the partial oxygen pressure is positive linearity.
Key words: copper oxide; FeO-rich slag; dissolution behavior
