Particle size distribution (PSD) of the selected pure copper powders, from laser diffraction analyses (provided by LPW Technology Ltd); corresponding SEM images below each PSD. Finally, laser absorption measurements were carried out on a Jasco V-570 spectrophotometer with integrating sphere ISN-470 ( max range 200-2000 nm).

Generalized Particle Size Distributions B.2.1 Rationale For Developing Generalized Particle Size Distributions The preparation of size-specific particulate emission inventories requires size distribution information for each process. Particle size distributions for many processes are contained in appropriate industry sections of this document.

particle size on the reaction behaviour of each concentrate were studied. The reaction products were analyzed for copper, iron, and sulfur to determine the fraction of original sulfur remaining as a measure of the extent of reaction and the Cu/Fe ratio as a measure of copper volatilization. X-Ray Diffraction was employed to identify the phases

Abstract Concentrations of heavy metals, pH, and particle size distribution parameters were measured in Dragica stream and Djetinja River water receiving wastewaters from copper rolling mill industry, Sevojno. The concen-trations of copper, zinc, lead, and mercury were determined for water samples collected in summer 2009. It was found
