Dec 26, 2018Pure black minerals are less common than other types of minerals, and they can be difficult to recognize. But by carefully observing such things as grain, color, and texture, you can easily identify many black minerals.This list will help you identify the most significant of them, along with notable geological characteristics, including luster and hardness as measured on the Mohs Scale.

The minerals from which metals can be extracted are called ore minerals, or economic minerals. These minerals contain metal in high concentrations and in a form that can be easily extracted. Galena (PbS), for example, is about 50% lead, so we consider it to be an ore mineral of lead (a in figure above).

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
