Flowability of Electrolytic Copper Powder
Materials Science Forum, 2005The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density is higher than 2.2 – 2.3 g/cm3.

The apparent density and flowability of copper powder are related to the structure of powder particles and the reversing current (RC) regimes. It was shown that the apparent density of the powders increases with the increase in the compactness of particles, hence with the increase in the frequency of RC and with the decrease in the cathodic to anodic ...

Increasing the flowability of electrolytic copper powders
Soviet Powder Metallurgy and Metal Ceramics, 1989As automatic production lines are being introduced in powder metallurgy, the requirements for materials change, in particular the demand for copper powders of high flowability grows. The currently used electrolytic copper powders have a well-developed dendritic structure, and exhibit virtually no flowability. After mechanical processing not more than 5%

Recovery of copper powder from copper bleed electrolyte of an Indian copper smelter by electrolysis
Minerals Engineering, 2007Copper bleed solution generated from an Indian Copper smelter contains high amount of copper and nickel along with several impurities. Attempts have been made to develop a new process for the production of pure copper powder from such streams.

Effect of electrolyte characteristics on electrowinning of copper powder
Journal of Applied Electrochemistry, 2009This paper is concerned with studying the effect of electrolyte characteristics on the production process of electrolytic copper powder from partially depleted Cu containing synthetic electrolytes by electrowinning technique. The main electrolyte characteristics are temperature, circulation rate, Cu and H2SO4 concentrations, residence time in the cell,
