2. Copper electroplating - Wikipedia

   en.wikipedia.org/wiki/Copper_electroplating

   PCBs being fabricated in an industrial copper pattern plating line. Excluding the continuous strip plating industry, copper is the second most commonly-plated metal after nickel. [6] Copper electroplating offers a number of advantages over other plating processes, including low metal cost, high-conductivity and high-ductility bright finish, and ...

3. Electrochemical coloring of metals - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_coloring...

   cathode made of platinum or stainless steel (needle), anode nickel-plated or gold-plated copper or brass or polished steel, duration 10 s, distance between cathode and anode 3 mm . [20] An electrolyte of 100 g of litharge dissolved in 0.5 l of water can also be used in which 100 g of NaOH is dissolved.

4. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure. Zinc sacrificial anode (rounded object) screwed to the underside of the hull of a small boat. Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an ...

5. Electroplating - Wikipedia

   en.wikipedia.org/wiki/Electroplating

   Simplified diagram for electroplating copper (orange) on a conductive object (the cathode, "Me", gray). The electrolyte is a solution of copper sulfate, CuSO 4 in sulfuric acid. A copper anode is used to replenish the electrolyte with copper cations Cu 2+ as they are plated out at the cathode.

6. Electrotyping - Wikipedia

   en.wikipedia.org/wiki/Electrotyping

   Schematic apparatus for electrotyping. An electric current flows from the battery, through the copper anode, the electrolyte, and the coated mold. A copper film (the electrotype) grows onto the electrically conducting coating of the mold. Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model.

7. Electrowinning - Wikipedia

   en.wikipedia.org/wiki/Electrowinning

   In electrowinning, an electrical current is passed from an inert anode through a leach solution containing the dissolved metal ions so that the metal is recovered as it is reduced and deposited in an electroplating process onto the cathode. In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure ...

   After three years, the anodes simply need a new coat of catalysts made from affordable, earth-abundant elements to make them as good as new, lasting for decades. “This breakthrough is the crux of Equatic’s ability to scale to gigaton volumes and has global implications,” emphasized Edward Sanders, chief operating officer at Equatic.

9. IsaKidd refining technology - Wikipedia

   en.wikipedia.org/wiki/IsaKidd_refining_technology

   A modern copper refinery tankhouse using IsaKidd technology. The IsaKidd Technology is a copper electrorefining and electrowinning technology that was developed independently by Copper Refineries Proprietary Limited (“CRL”), a Townsville, Queensland, subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies), and at the Falconbridge Limited (“Falconbridge ...
