copper extraction and purification - chemguide
2015-7-26 The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.

Speciation studies of copper and magnesium in
2018-6-3 Abstract Studies on duckweed extract indicated that at least some of the magnesium in chlorophyll was replaced by copper. The copper combined not only with chlorophyll, but also with some other plant pigments in duckweed. The study also demonstrated that HPLC‐AA can be used to study the speciation of the copper and magnesium in duckweed, revealing the total number of such compounds
