| 中文摘要 | 濕法冶金(Hydrometallurgy)目前已被廣泛地應用在煉銅工業上,此乃由於該法所消耗之能源、環境污染及公害之問題遠較乾法冶金(Pyrometallurgy)少,同時亦比較經濟。溶劑萃取為濕法冶金之主要單元,本實驗係用此法研究自煉銅之陽極泥中回收銅之化學程序,所用之專利有機溶劑為美國灰土公司(Ashland Chemical Co.)的 KELEX 100,120及美國奇美公司(General Mills Chemicals, Inc)的 LIX64N,並以煤油為稀釋劑。先用硫酸將陽極泥中之銅浸漬出來,然後再作系列之萃取平衡實驗,由實驗數據再計算其連續萃取操作之理論階數。連續萃取操作所用之儀具為混合澄分器(Mixer-settler Extractor)及攪拌萃取塔(Agitated Extraction Column)。系列之實驗結果及建議之最佳操作條件亦提出報告。 |
| 英文摘要 | The current greatly increased interest in the application of hydrometallurgy in the chemical smelter of copper is due to the facts that: (1) energy costs have soared, and (2) the water and air pollution are typically less troublesome than those normally associated with the corresponding pyrometallurgical operations. Solvent extraction is one part of the hydrometallurgical processes for refining metals. This paper studied the chemical process for the recovery of copper from copper refinery anode slime, Ashland's product KELEX 100 and 120 and General Mill's Product LIX 64 N were used as the organic solvents and kerosene as the diluent. Extraction isotherm was done by equilibriating the leached copper sulfate solution and the organic solvent. The theoretical number of extaction stages can be determined then. The continuous operation of copper extraction and stripping were also done by using tube-type, pyrex glass mixersettler and an agitated extraction colume. Experimental results as well as the optimum conditions were reported. |
