Answered: Many mining operations produce tailings. | bartleby

One chemical that reacts in this way is chalcopyrite, CuFeS2, whose net oxidation can be described by the following equation. 4 CuFeS2 (s) + 17 O2 (g) + 10 H20 (1) → 4 Fe (OH); (s) + 4 CuSO4 (ag) + 4 H2SO4 (aq) In a laboratory experiment to study weathering, a mining engineer put a 1.68 kg sample of CuFeS2 (s) near an empty 40 L container.

Mining Engineering Online - smenet

Chalcopyrite extraction in an aqueous acid medium occurs through solid transformations into distinct intermediaries. As intermediates, mineral phases CuS, Cu2 S and Cu5 FeS4 may generate in the leaching solution before CuFeS2 completely decomposes to Cu2+, Fe2+ and S0. Oxalic acid is a common organic acid, and it dissolves easily in warm water.
