Question
Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is false.<br>(i) Every mineral is an ore but every ore is not a mineral<br>(ii) Slag is product formed during extraction of metal by combination of flux and impurities.<br>(iii) Highly pure metals can be obtained by zone refining.<br>(iv) Carnallite is an ore of magnesium and sodium.
💡 Solution & Explanation
Step 1: Write down the chemical formulas for each mineral: Limestone is primarily calcium carbonate (CaCO3); Chalk is also CaCO3; Feldspar is a group of aluminosilicate minerals. Step 2: Dolomite is a double carbonate mineral with the chemical formula CaMg(CO3)2. Step 3: Since Dolomite contains both calcium (Ca) and magnesium (Mg), option (b) is the correct answer.
