1.Enhanced the purification of alloys (copper, nickel and cobalt) in the solution.

• 1.Enhanced the purification of alloys (copper, nickel and cobalt) in the solution.
• 2.Cementation of the above metal ions that is precipitation in the form of salt.
• 3. The specific consumption during cementation is reduced.
• 4. Ensures efficient operation in the production of equipment.
• The temperature pH environment plays an important role in making a zinc powder mixture.

In a zinc powder solution, silicic acid is in the form of a gel, which is removed from the pulp by filtration. Heavy particles make filtration difficult and contaminate the sediment.

• 1.Copper and cadmium are released during the first stage of cementation.
• 2. Medium voltage metals: Cu, Ag, Fe, Ni, Co, Pd.
• 3. Low voltage metals: Pt, Ru, Rh.
• The current strength is determined by the Tafel equation based on the magnitude of the stresses of the metal, the hydrogen potential and the zinc electrode potential.
