Answer 3

Why is chalcopyrite considered an ore while malachite is not?

Chalcopyrite, also known as copper pyrite, is considered an ore because it is a significant source of copper. On the other hand, malachite is not considered an ore because it is not a primary source of copper extraction.

Chalcopyrite is a copper iron sulfide mineral with the chemical formula CuFeS2. It is the most important copper ore and is widely distributed in various geological environments. Chalcopyrite contains a high percentage of copper, typically ranging from 34% to 38% It is commonly found in hydrothermal veins, igneous rocks, and sedimentary deposits.

Malachite, on the other hand, is a secondary copper mineral. It is a green carbonate mineral with the chemical formula Cu2CO3(OH)2. Malachite forms as a result of the weathering and oxidation of primary copper minerals, such as chalcopyrite, bornite, and covellite. While malachite does contain copper, it is not a primary source of copper extraction and is not considered an ore in the same way as chalcopyrite.

In summary, chalcopyrite is considered an ore because it is a primary source of copper extraction, while malachite is not considered an ore because it is a secondary copper mineral formed through the weathering and oxidation of primary copper minerals.
