| 中文摘要: |
| 含铜污泥还原熔炼过程产出金属铜相(Cu)和锍相(冰铜，mt)，铜、镍、金和银在两相中均有分布，统计了约100批次熔炼产品，分析其分布规律。结果表明，金、银在铜相中的分布系数(βAu Cu、βAg Cu)与铜在铜相中的分布系数βCu Cu呈正相关，说明铜相对金、银的捕集能力比锍强，且对金的捕集能力强于银；银分配系数LAg与铜、镍在铜相中的分布系数(βCu Cu、βNi Cu)呈正相关，金、银分配系数(LAu、LAg)与锍相中镍含量([Ni]mt)均呈弱负相关，说明锍相对银的捕集能力强于金。 |
| 英文摘要: |
| Copper phase (Cu) and matte phase (matte, mt) were formed during the reduction smelting process of copper-containing sludge. Copper, nickel, gold and silver were distributed in both phases. About 100 batches of smelting products were included in order to analyze their distribution rules. The results showed that the distribution coefficients of gold and silver in the copper phase (βAu Cu, βAg Cu) were positively correlated with the distribution coefficient of copper in the copper phase (βCu Cu), indicating that the catching ability of copper for gold and silver was better than that of matte whereas copper displayed a greater catching ability for gold than for silver. The distribution coefficient of silver LAg was positively correlated with those of copper and nickel in the copper phase (βCu Cu, βNi Cu). On the contary, the catching ability of matte for silver was better than that for gold, and a weak negative correlation was observed in the distribution coefficients of gold and silver (LAu and LAg) with the content of nickel in matte [Ni]mt. |
