摘要
在1873K条件下对铜在富FeO熔渣中的氧化溶解行为进行了研究。结果表明铜氧化物在富FeO熔渣中以Cu2O的形式存在;熔渣中CaO的含量将对铜的氧化溶解产生影响,随着渣中CaO含量的增加,熔渣中的铜含量逐渐下降,但在不同温度下,这种影响的作用各不相同;当温度较高时,渣中CaO含量对铜的氧化溶解影响较大,且随着温度的降低,其影响作用明显变缓;反应体系的氧分压对铜的氧化溶解影响较大,在熔渣中γ(CuO0.5)不变的情况下,铜氧化物的溶解与体系氧分压的四分之一次方之间呈正线性关系。
The oxidation dissolution behavior of copper in the FeO-rich slag at 1873K was investigated. The results show that the copper oxidate is Cu_2O. 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.
