Nov 01 2009 The zoning from Cu ores to Zn Pb ores is complex and comprises a number of distinct and well defined zones that display abrupt or gradual interfaces between zones. From internal to external parts these zones consist mainly of the following mineral associations and assemblages 1 enargite ± luzonite pyrite colusite tennantite

Mar 05 2017 Copper in fact is known as a noble metal and is fairly resistant to oxidation while zinc is one of the most easily oxidized of metals. For this reason it is commonly used as the anode site of oxidation and source of electrons in an electrochemical cell such as a dry cell battery . Answer link.

Correlation analysis showed that these four extractants can provide a good indication of the toxicity of Cu Zn Cd and Pb in the amended sediment. Additionally the organic matter content in the amended sediment decreased by 1.4 for CK 1.6 for L0.5 1.7 for L1 1.5 for L2 1.5 for L5 1.9 for L10 and 1.9 for L20 CK untreated sediment
