Which of the following combinations of ores and their primary concentration or beneficiation methods — Metallurgy and Isolation of Elements Chemistry Question
Question
Which of the following combinations of ores and their primary concentration or beneficiation methods are correctly matched based on their specific chemical or physical properties?
Answer: A,B,C
💡 Solution & Explanation
Cassiterite contains magnetic impurities (Wolframite) and is separated magnetically. Galena is a sulphide ore, naturally suited for froth flotation. Bauxite is concentrated chemically via leaching (Baeyer's/Hall's). Haematite is an oxide ore and is typically concentrated by gravity separation, not froth flotation.
