Pocket knives, paper clips, and iron nails generally have a hardness of 5.5-6.5. Glass can be scratched by any mineral harder than ~5.5. A US copper penny has a hardness of 3.0 and human fingernails have a hardness of ~2.5. By using these common objects you can determine the relative hardness of your mineral specimen with some degree of accuracy.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
