The Extraction of Copper Chemistry LibreTexts

Purifiion of copper. When copper is made from sulfide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulfur (trapped as bubbles of sulfur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis.
