Electrolytic Extraction of Copper, Molybdenum and
2017-7-20 Electrolytic extraction of copper, molybdenum, and rhenium was conducted successfully at 1500 K using an electrolyte composed of alkaline-earth, rare-earth, and copper sulfides. The addition of a rare-earth metal sulfide component to the electrolyte increased the faradaic efficiency and the recovery/isolation of sulfur as the anodic product.

2017-6-28 Doubling efficiency. The new work doubles the efficiency for electrolytic extraction of copper reported in the first paper, which was 28 percent with an electrolyte where only barium sulfide added to the copper sulfide, to 59 percent in the second paper with both lanthanum sulfide and barium sulfide added to the copper sulfide.

2015-7-26 Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis. Electrolytic refining
Electrolytic production of copper from chalcopyrite

Electrolytic production of copper from chalcopyrite
The electrolytic extraction of liquid copper at 1105 C from a molten sulfide electrolyte composed of 57 wt% BaS and 43 wt%Cu2S was investigated. DC cyclic voltammetry, Fourier transformed AC

2017-12-7 The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99% through an electrolysis process: During electrolysis, copper (II) ions leave the impure copper anode and since they are
Electrolysis of copper(II) sulfate solution Experiment
In this practical, students carry out the electrolysis of copper (II) sulfate solution. The outcomes of the experiment provide the opportunity to introduce a discussion about electroplating and the industrial electrolytic refining of copper. This class experiment can be done by
