A new way of extracting copper

Jun 28, 2017· 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.

Extractive Metallurgy of Copper

Pure copper metal is mostly produced from these ores by concentration, smelting, and refining About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide or The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite or.

Copper production & environmental impact

Whereas, theoretically copper is finite resource and extraction will reach a peak, the timing is subject of debate Confounding the imminent 'peak copper' argument is the fact that continually discovered reserves combined with increasing efficiency of extraction means that, for now, known and speculated quantities of copper far extend beyond.
