METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER …

Blister copper is refined by electrolysis. Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in …

The Extraction of Copper - Chemistry LibreTexts

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.

Extractive Metallurgy of Copper | ScienceDirect

The total direct plus indirect cost of producing electrowon copper cathodes from oxide and chalcocite ores (including mining) is $1–$2 per kg of copper. Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for …

copper processing | Definition, History, & Facts ...

Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a “ blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.
