JEE Main · 2019 · 11 Jan 2019 · Shift 1 · General Principles and Processes of Isolation of Metals

Match the ores (column A) with the metals (column B)

Answer: A → III, B → IV, C → II, D → I

Solution

Pair each ore with the metal it yields. Siderite is iron(II) carbonate,

FeCO X_{3}

, an ore of iron. Kaolinite is an aluminosilicate clay, an ore of aluminium. Malachite is the green basic copper carbonate, an ore of copper. Calamine is zinc carbonate,

ZnCO X_{3}

, an ore of zinc. So siderite goes with iron, kaolinite with aluminium, malachite with copper and calamine with zinc.
