Purpose of Chemical Reactions in Producing Nickel (Mond's Process)
1. CO → Fe(s)
- Purpose: Reduction
- Beneficiation: This reaction is not directly involved in the beneficiation of nickel. It is used for the production of iron, which is one of the components of Mond's process.
- Explanation: Carbon monoxide (CO) is used to reduce iron oxide (Fe2O3) to produce iron (Fe) in the solid state. The reaction can be represented as follows:
3CO(g) + Fe2O3(s) → 2Fe(s) + 3CO2(g)
The iron produced in this step is further used in the subsequent reactions to produce nickel.
2. Co(s)
- Purpose: Reduction
- Beneficiation: This reaction is not directly involved in the beneficiation of nickel. It is used for the production of cobalt, which is one of the components of Mond's process.
- Explanation: Cobalt (Co) is produced by the reduction of cobalt oxide (CoO) using carbon monoxide (CO) gas. The reaction can be represented as follows:
CoO(s) + CO(g) → Co(s) + CO2(g)
The cobalt produced in this step is further used in the subsequent reactions to produce nickel.
3. [Ni(CO)4](g); then heat gas → 4CO(g) Ni(s)
- Purpose: Chemical Conversion and Purification
- Beneficiation: This reaction is directly involved in the beneficiation of nickel.
- Explanation: In this step, nickel tetracarbonyl ([Ni(CO)4]) gas is heated to decompose it into carbon monoxide (CO) gas and pure nickel (Ni) metal. The reaction can be represented as follows:
[Ni(CO)4](g) → 4CO(g) + Ni(s)
This reaction helps in the purification of nickel by converting a nickel compound into its pure metallic form. The pure nickel obtained in this step can be further processed and refined for various applications.
Purpose of Chemical Reactions in Producing Copper
1. Electrolytic Oxidation: Fe²(aq) Cu²(aq) Ag(s) Au(s)
- Purpose: Purification
- Beneficiation: This reaction is not directly involved in the beneficiation of copper. It is used for the purification of copper, as well as the recovery of silver and gold.
- Explanation: In this electrolytic oxidation step, a solution containing copper ions (Cu²+), iron ions (Fe²+), silver metal (Ag), and gold metal (Au) is subjected to an electric current. The copper ions are oxidized and deposited onto the cathode, while the iron ions, silver metal, and gold metal remain in the solution. This process helps in purifying copper by removing impurities and obtaining pure copper metal.
2. Electrolytic Reduction: Cu(s) Fe²(aq)

Purpose of Chemical Reactions in Producing Nickel (Mond's Process)
1. Beneficiation: CO → Fe(s)
- The purpose of this reaction is beneficiation, which involves the separation and removal of impurities from the metal ore.
- In Mond's process, carbon monoxide (CO) is reacted with the impure nickel to form solid iron (Fe), which can be easily separated from the desired nickel.
2. Chemical Conversion: Co(s) + [Ni(CO)4](g) → 4CO(g) + Ni(s)
- The purpose of this reaction is chemical conversion, where one chemical species is converted into another.
- Cobalt (Co) reacts with nickel tetracarbonyl ([Ni(CO)4]) gas to form carbon monoxide (CO) gas and solid nickel (Ni).
- This reaction allows the extraction and isolation of pure nickel from the impure mixture.
3. Purification: Heat gas → 4CO(g) + Ni(s)
- The purpose of this step is purification, which involves the removal of any remaining impurities from the metal.
- By heating the gas mixture of carbon monoxide (CO) and nickel (Ni), the impurities are driven off, leaving behind purified nickel.
Purpose of Chemical Reactions in Producing Copper
1. Electrolytic Oxidation: Fe²(aq) + Cu²(aq) → Cu(s) + Fe²(aq)
- The purpose of this reaction is electrolytic oxidation, which involves the oxidation of one metal species while reducing another metal species.
- In this case, iron (Fe) ions are oxidized to iron(II) ions (Fe²+), while copper (Cu) ions are reduced to solid copper (Cu) during the electrolysis process.
- The oxidation of iron allows it to be removed from the solution, while the reduction of copper leads to the deposition of pure copper metal.
2. Electrolytic Reduction: Cu(s) + Fe²(aq) → Cu(s) + Fe²(aq)
- The purpose of this step is electrolytic reduction, where the desired metal species is selectively reduced from a solution.
- Copper ions (Cu²+) in the solution are reduced to solid copper (Cu) at the cathode electrode, while iron(II) ions (Fe²+) remain in the solution.
- This process allows for the purification and deposition of pure copper metal.
In summary, the chemical reactions involved in producing nickel (Mond's process) and copper serve different purposes. The reactions in the Mond's process involve beneficiation, chemical conversion, and purification, while the reactions for copper production involve electrolytic oxidation and electrolytic reduction. These reactions help in the extraction, separation, and purification of the desired metals from their respective ores or solutions.
