Electrolytic Refining of Copper - Unacademy

2 天之前 Electrolytic refining is the method in which electricity is used to refine impure metals. The anode is made from impure copper and the cathode from pure copper. Copper sulphate acidified with sulphuric acid is used as an electrolyte. By passing electric current, impure metal dissolves from the anode into the electrolytic solution.

Effect of typical impurities for the formation of floating slimes

2017.11.10 The lack of high-purity ores has made the copper industry exploit low-impurity ores containing As, Sb and Bi which can affect the final product quality due to the floating insoluble arsenates. This is usually solved by treating the electrorefining electrolyte in a polishing stage devoted to removing Sb and Bi using aminophosphonic resins.

Electrolytic Refining of Copper - An Overview

2022.12.22 Electrolytic Refining. Electrolytic refining is a process that takes place in an electrolyte bath, which consists primarily of sulfuric acid and copper sulfate solution. An anode, made from pure copper, is placed into the bath, and a current is passed through it. The anode becomes the cathode, while the impure copper becomes the anode.

Impurity control and removal in copper tankhouse operations

During copper smelting, most of the undesirable impurities such as Pb, Sb, Bi, and As are only partially removed by oxidation. When white metal and blister copper are in equilibrium, these impurities are distributed mainly into the copper phase, from which their removal is difficult. When copper dissolves during electrorefining in a copper tankhouse, these
