Chapter 3 The Business Structure of the Copper Industry

of the Copper Industry The structure of the world copper industry has changed significantly during the last 25 years. Rapid growth in world copper demand began in the industrialized countries following World War II, and then shifted to the less developed coun-tries. This led to the construction of significant new copper production capacity, Initially this

Synthesis and Characterization of Copper(II) Complexes ...

Copper complexes were obtained in situ from ligand solution as greenish powders. All the complexes were characterized by infrared spectroscopy, UV-vis, powder X-ray diffraction and Scanning Electron Microscopy. The complexes show an amorphous phase in the case of DCu12 and nanocrystalline structure for DCu18, as observed in XRD.

REMOVAL OF LEAD FROM THE INDUSTRIAL AND SYNTHETIC Cu

quantity of lead in dusts and obtainment of low concen-tration of arsenic in copper. As result of this process, approx. 70 % wt. of lead contained in this alloy is pass-ing to dusts, and the remaining part is collected in con-verter slag. Because the copper content in slag (even above 35 % wt.) is higher than that of lead, this material
