Rocks and Minerals

Oct 02, 2019Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3D objects, or knowing rates of crystallization.

Ore Deposit

Ore deposits are rarely comprised of 100% orebearing minerals, but are usually associated with rockforming minerals during the mineralization process. These associated minerals or rocks, having no significant or low commercial value, are called gangue minerals. Pure chalcopyrite having % Cu metal in copper deposit and sphalerite with 67% Zn metal in zinc deposit are hosted by quartzite

Rock Identification Guide

The sheer number and variety of rock and mineral samples required for the production of the units is immense. More than 60 samples representing 25 different types of metallic and industrial minerals, aggregates and the three main rock groups – igneous, sedimentary and

Copper

Secondary ores, called oxide ores, formed as weather and other natural forces altered ancient rocks. Both types of ore are mined and processed to extract the copper. Primary ore minerals of copper include malachite, azurite, chalcocite, bornite, and cuprite. One of the more familiar and beautiful minor ore minerals of copper is chrysocolla.

What are the differences between minerals and ores?
