Apr 14, 2016 The cement copper is normally sacked for shipment. Theoretically one pound or iron will precipitate 1.137 pounds of copper while in actual practice two to three times this amount is required especially if the iron used is highly oxidized. Sponge iron is usually more effective and consumption is often equal to weight of copper precipitated.
