Producing area - Ore

Question

Which one of the following is not matched correctly? 
Producing area - Ore

Accepted Answer

Magnitogorsk is not correctly matched with Chromium. Here's why:

*   **Magnitogorsk - Chromium (Incorrect):** Magnitogorsk, located in Russia, is primarily known for its massive iron ore deposits and steel production. It was built around Mount Magnitnaya, a mountain rich in iron ore. While some chromium might be present in the region, it is not the primary ore associated with Magnitogorsk. The city's historical and economic significance is overwhelmingly tied to iron and steel.

Now, let's explain why the other options are correctly matched:

*   **Chuquicamata - Copper (Correct):** Chuquicamata, located in Chile, is one of the world's largest open-pit copper mines. It is renowned for its massive copper deposits and is a major producer of copper.

*   **Krivoy Rog - Iron (Correct):** Krivoy Rog, located in Ukraine, is a major iron ore mining region. It has significant iron ore deposits and has been a center for iron ore extraction and processing for a long time.

*   **Orinoco Basin - Petroleum (Correct):** The Orinoco Basin, primarily located in Venezuela, contains vast reserves of petroleum, particularly extra-heavy crude oil. The Orinoco Oil Belt is a major area for petroleum production.

Therefore, the only mismatched pair is Magnitogorsk - Chromium, as Magnitogorsk is primarily associated with iron ore, not chromium.
