Copper is one of few metals that can occur naturally in its native metallic form. This is different from most metals that need to be extracted via metallurgy from an ore. In places where native copper occurs, the technology of metallurgy was not necessary for those civilizations to begin to work with copper to form weapons and ornaments.

Thus the loss of copper as oxide increases as the copper content of the matte increases. On the other hand, the solubility of copper sulfide in slag decreases as the copper content of the matte increases beyond about 40%. The loss of copper as prills depends on the size of the prills, the viscosity of the slag and the settling time available.

The average crystallite size extracted from the broadening of all peak widths labeled in Fig. 1 a using the Scherrer equation is about 49 nm for milled powder, versus 56 nm for raw ones [12, 13]. Obviously, the milling does not pose much effect on reducing the crystallite size; but, importantly, it does affect the particle size significantly.
