Q1: Which of the following is not an ore of iron ?A Chalcopyrite
B Magnetite
C Hemetite
D Limonite
ANS:A - Chalcopyrite Chalcopyrite is not an ore of iron; it is an ore of copper. Chalcopyrite is a copper iron sulfide mineral that is commonly found in copper ore deposits. While it does contain some iron, its primary economic significance lies in its copper content. Therefore, it is not classified as an ore of iron. The other options listed—Magnetite, Hematite, and Limonite—are all ores of iron. They are iron oxides or hydroxides commonly mined for their iron content. So, the correct answer is Chalcopyrite. |
