Novel Electrochemical Milling Method To Fabricate Copper
Sep 24, 2005 With decreasing the discharge current, the morphology and particle size of ECM-derived copper can be elegantly tailored from spherical nanoparticles to dentritic nanofibers. Novel Electrochemical Milling Method To Fabricate Copper Nanoparticles and Nanofibers Chemistry of

US6322672B1 Method and apparatus for milling copper
A method of enhancing charged particle beam etching particularly suitable for copper interconnects, includes milling at non-contiguous locations to prevent the formation or propagation of an etch-resistant region within the rastered area. Two or more milling boxes are typically performed, one or more of the boxes having pixel spacing greater than the spot size, with the last box using a

Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years. Moreover, six of the mines opened be-tween 1900 and 1920 are still among the major copper producers in the United States today.

Machining copper Practical Machinist
Mar 01, 2010 I have found that full cream milk is the best cutting fluid for copper both milling and turning don't use skim as it needs the fat content. You will need to experiment with your speeds and feeds. What kind of cuts do you need to make to get it to size and how thick is the material ?
