Copper (Cu, Z=29) Copper is a malleable, ductile, reddish-brown metal. Its name is derived from the Old English name coper, which is in turn derived from the Latin word cuprum for "from the island of Cyprus," which was the leading supplier of copper in the Mediterranean area at the time of the Roman empire.
· Gold mining can be open-pit or deep shaft mixed with other HM such as copper (Cu), silver (Ag) and lead (Pb). Its location determines the type of mining process to be used in extraction and the amount of wastes that will be generated. In the past, small quantities of waste were generated by mining activities because higher grade ores were being exploited. There
Zn, Cu, Mn, Cd: Gan et al., 2022: Copper ore: Metallosphaera sedula: Cu: McCarthy et al., 2022 : Although bioleaching is well established for sulfide minerals, recycling metals from E-waste is much more challenging. There are obviously differences between sulfide minerals and E-waste in terms of their physical and chemical properties and structures, and E-waste contains toxic

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough
