Alternate Anode Reaction for Copper Electrowinning

The conventional copper electrowinning process uses the water hydrolysis reaction as the anodic source of electrons However this reaction generates acid and oxygen gas The oxygen which leaves the system is associated with some acid from the electrolyte resulting in an acid mist

ARSENIC’S BEHAVIOUR AND BENEFITS IN COPPER ELECTROREFINING

The concentration of arsenic in anodes varies widely depending on the copper source The typical anode arsenic concentration reported by 35 copper refineries is presented in Figure 1 (Moats Robinson Wang Filzwieser Siegmund & Davenport 2013) Anode composition ranges from 7 to 1800 ppm with an average of 870

What is electrolytic refining?
In this setup, an electrolyte (metal salt aqueous solution), depending on the metal, is often used. The clean or pure metal is formed at the cathode when the electrical current of a sufficient voltage is applied by dissolving impure metal at the anode. Electrolytic refining is also sometimes referred to as electrorefining.
Can low-grade chalcopyrite be used for copper production?
A vision is proposed in which an electrolytic technique, integrated with low cost and sustainable power, enables the production of unprecedented annual tonnages of copper from low-grade chalcopyrite, with valuable by-products and enhanced selectivity for impurities. 1. Introduction
Can copper be purified by electrolytic refining?
Even small concentrations of impurities noticeably lower copper’s electrical conductivity. Such a high degree of purity can be obtained by electrolytic refining in a cell similar to that shown in Figure 17.5.1 17.5. 1. Figure 17.5.1 17.5. 1: The electrolytic purification of copper.
How can a high degree of purity be obtained by electrolytic refining?
Such a high degree of purity can be obtained by electrolytic refining in a cell similar to that shown in Figure 17.5.1 17.5. 1. Figure 17.5.1 17.5. 1: The electrolytic purification of copper. In such a cell a thin sheet of high-purity Cu serves as the cathode, and the anode is the impure Cu which is to be refined.
