A Closer Look at Float Copper: A Journey From The Ice Age
So native copper is essentially copper that existed in an elemental form before removal from its original area. Copper is rarely found in this form, due to its high chemical reactivity. Much of the time when copper is found the deposit is in the form of malachite or other copper ores that are the usual source of the metal.

A commercially available near-spherical copper powder with a particle size of 30–160 μm (purity >99 %) was used for laser cladding. Fig. 1 shows the surface morphology and size distribution of pure Cu powders. Prior to laser cladding, the pure Cu powders were dried in a furnace at 120 °C for 1 h to remove moisture.
