Minerals | Free Full-Text | Industrial Heap Bioleaching of Copper
Sulfuric acid solution containing ferric iron is the extractant for industrial heap bioleaching of copper sulfides. To start a heap bioleaching plant, sulfuric acid is usually added to the irrigation solution to maintain adequate acidity (pH 1.0–2.0) for copper dissolution. An industrial practice of heap bioleaching of secondary copper sulfide ore …

Copper Smelting and Refining Process | Pan Pacific Copper
The SO 2 gas is first recovered from the waste heat boiler. After electrostatic precipitators remove dust particles in the gases, the gas is transferred to the sulfuric acid plant. At the sulfuric acid plant, the catalytic reaction of vanadium oxides causes SO 2 to oxidize into SO 3, which is absorbed in water to yield concentrated sulfuric acid.
