Reasina Suvaroporn MASC 110L – 2/17/09 Experiment 3: Thermal Reduction of Copper Ore to Copper Metal Objective: To learn step-by-step about the transformation from copper ore to copper metal through thermal process Theory: First of all, this experiment occurs simply because Reduction Reaction which means the ability to reduce naturally occurring minerals to metallic metal, in this case Copper. In order to transform mineral to metal, there are 2 very important parameters that were involved. (1). High temperature: to drive off carbon dioxide and water from Malachite to produce Copper(II) Oxide Cu 2 CO 3 (OH) 2 2CuO + CO 2 + H 2 O {Color: Black} (2). Presence of Carbon: to produce copper metal {Tm Cu = 1084ºC} CuO + C Cu + CO Carbon is used in the second step to reduce copper(II) oxide to metallic copper. Result: In class Q7). Atomic Mass Cu 2 CO 3 (OH) 2 = 221.12 g/mol CuO = 79.55 g/mol Initial Weight Weight of Crucible: 23.05 g Weight of Both: 24.66 g Weight of Malachite: 1.61 g
