The seller supplied a copy of an analysis indicating them to be 94.8% copper, but not saying what the rest was, other than that it wasn't palladium, platinum, or rhodium. I confirmed the analysis by x-ray fluorescence spectroscopy at the Center for Microanalysis of Materials, University of ...
Fine Yin-Shang bronzes containing lead with puzzlingly highly radiogenic isotopic compositions appeared suddenly in the alluvial plain of the Yellow River around 1400 BC. The Tongkuangyu copper deposit in central China is known to have lead isotopic comp

Copper sulfide ore is the main raw material for pyrometallurgy at present, but the mining grade is getting lower and lower; therefore, low-grade sulfide ore, compound ore, oxide ore and tailings will become the main resources for copper smelting in the future. And this kind of ore cannot be...
Towards this goal, this paper presents a review of the distribution behavior of five critical elements (selenium, tellurium, arsenic, antimony and bismuth) through the primary copper pyrometallurgical supply chain. This review identifies gaps in the distribution/concentration data of these elements in ...
Electronegativity is a key property of the elements. Being useful in rationalizing stability, structure and properties of molecules and solids, it has shaped much of the thinking in the fields of structural chemistry and solid state chemistry and ph
