銅電解精煉的目的不僅要獲取高純度的金屬,而且还要提煉和利用那些含在粗銅中作為雜質的有價金屬,其中包括貴金屬。 銅電解精煉是用粗銅作為可溶陽極,用硫酸銅的酸性溶液(用硫酸進行酸化)作為電解液。当槽電压在0.25～0.3伏特時,銅於陽極上溶解並沉積於陰極卽薄銅板上。当銅板達到一定重量時,就用新的來替换。这時部分雜質轉移列電解液中,而絕大部分雜質成為陽极泥形態落到槽的底部。我們用電解精煉工廠電解車間的技術操作計算為例,來
The purpose of copper electrolytic refining is not only to obtain high-purity metals, but also to extract and utilize those valuable metals contained in blister copper as impurities, including precious metals. Copper electrolytic refining is the use of blister copper as a soluble anode, with an acidic solution of copper sulfate (sulfuric acid acidification) as the electrolyte. When the cell voltage is between 0.25 and 0.3 volts, the copper dissolves on the anode and deposits on the cathode and thin copper plate. When the copper reaches a certain weight, replace it with a new one. At this moment, some impurities are transferred into the electrolyte, and most of the impurities fall into the shape of anode mud and fall to the bottom of the trough. We use electrolytic refining plant electrolysis plant technical operations as an example, come
