Dissolution of copper and iron from malachite ore

2014-3-1  For each experiment, 40 mL of various sulfuric acid solutions of 0.4–2.0 M and 10 g of ore sample were employed to dissolve the copper and iron incorporated in the malachite ore. Then, the impure copper solution was treated with hydrogen peroxide (H 2 O 2 ) to ensure that all iron (II) ions were converted to iron (III).
