Oxide Ores. The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition.

3 Major Periods of Metal Age Copper, Bronze and Iron Age

The first copper tools from native copper ore were made in the same manner as the stone tools were made in Neolithic Age. Pounding i.e. application of the method of cold hammering drew the shapes. The implements include simple flat axes and daggers. The nature as well as the limited number of the tools suggests that the people of the particular period did not know the art of smelting, casting

Copper Statistics and Information USGS

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores. Copper is one of the oldest metals ever used and has been one of

Abstract USGS

This method usually has a lower operating cost per short ton than any other underground method, and often the highest capital cost. The ore body must have enough horizontal area to cave freely, without dilution from the sidewalls. Large massive deposits are most suited for block caving. Vein deposits must be wide-typically greater than 100 ft-with a steep dip. Ore grades should be fairly
