The membrane process achieved high water fluxes (15.5 ± 0.2 L⋅m − 2 ⋅h − 1 ), salt rejections (98 %) while precious metal recovery (91 %) was achieved through adsorption processes [15].
Chemical mechanical planarization (CMP), which can globally planarize both silicon dioxide (the prevalent interlayer dielectric), and copper films, has become the key process in the damascene method used for producing integrated circuit (IC) devices with multilevel copper interconnects. Cu CMP is typically carried out with slurries containing oxidizing agents, …

Examination of the Ellingham diagram shown in Figure (PageIndex{2}) illustrates why the metals known to the ancients were mainly those such as copper and lead, which can be obtained by smelting at the relatively low temperatures that were obtainable by the methods available at the time in which a charcoal fire supplied both the heat and the carbon.
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of ...

In each case, feature geometry as well as plating time affect how additives behave. Dual Damascene Plating
Impurity levels are usually controlled by "bleeding". Bleeding is the process of removing a small fraction of solution for impurity removal. Generally, in copper electrowinning the "bleed" solution is sent to a liberator cell. Much of the remaining copper is electrolytically removed in the liberator cell.
