  The electrowinning process is a commonly used method to extract metals from ore. The titanium electrodes are used as anodes in this process to provide the electrical current needed for the extraction of titanium.

• Titanium coated iridium

  As mentioned, these electrodes are coated with iridium oxide and are often applied due to their durability and inertness. They are especially useful in electrochemical processes of mining with acidic leach solutions. These include uranium and copper mining, where the leach solution is often in a low pH range.

• Ruthenium iridium

  These electrodes are coated with a mix of ruthenium and iridium oxides. This particular combination increases the anodic overpotential and electrocatalytic activity of the electrode. These electrodes are often used in mineral electrowinning processes. These processes include vanadium and chromium extraction.

• Titanium coated platinized

  These electrodes are coated with platinized tungsten. These electrodes are used in environments that require high efficiency and Thompson process electrolytic cell longevity. The Platinized titanium anodes are especially useful in the processing of precious metals.

Commercial use of titanium MMO electrode

Titanium MMO electrodes are essential in different industries for metal extraction and wastewater treatment.

• Chloride process titanium

  The chlorate process involves extracting aluminium and magnesium from seawater or brines. In this process, titanium MMO electrodes are used to produce chlorine gas. It helps separate sodium chloride into magnesium and sodium carbonate. The electrodes increase the efficiency and production rate of the process.

• Hydrometallurgy

  Hydrometallurgy helps extract metals from ore using aqueous solutions. Titanium MMO electrodes work as the anodes in mineral electrowinning, which applies a direct current to deposit metals from electrolyte solutions onto cathode plates. This helps recover copper, uranium, and other metals in a cost-effective manner.

• Electrowinning and electrorefining

  In electrowinning, the dissolved metal ions are reduced and deposited as metallic solid on the cathode during electrorefining. The titanium MMO electrodes serve as anodes to facilitate copper, nickel, and cobalt electrorefining. This purifies the metals and recovers them from solutions in nickel-copper and copper mining.

• Wastewater treatment

  Titanium MMO electrodes are used in an electrochemical treatment method that removes contaminants from industrial wastewater. The anodes generate oxidizing agents. These agents help precipitate heavy metals or oxidize organic pollutants. They are used in wastewater treatment plants. These plants help purify water collected from mining, metal plating, or chemical manufacturing operations.

• Corrosion protection

  Titanium MMO electrodes are used to prevent cathodic corrosion on infrastructure like pipelines, ships, and offshore platforms. They generate a protective electric current that inhibits metal loss and prolongs the asset's lifespan. Commonly used in oil and gas, marine, and chemical exposure environments for cost-effective long-term corrosion protection.

How to choose titanium MMO electrode

Here are some of the key factors that buying customers should consider when choosing titanium electrodes for sale.

• Commercial use

  These electrodes are used for several industrial processes. Some of these processes include metal extraction, electroplating, and wastewater treatment. Each of these applications places different requirements on the electrode.

  For instance, electrodes used in gentle conditions do not need to be highly catalytically active. However, electrodes used in wastewater treatment should be highly catalytically active. A customer whose electroplating business is experiencing anode shortages should hence stock up on titanium MMO electrodes. These electrodes are commonly used in electrolyte baths for metal deposition.

• Working environment

  Titanium MMO electrodes have different coatings that make them suitable for different electrolytic environments. Dissolved titanium coated electrodes are suitable for strongly acidic solutions.

  Conversely, ruthenium-coated titanium MMO electrodes are suitable for mildly acidic to neutral environments. Iridium-coated electrodes are ideal for diluted or low-current electrolytic cells.

  Electrodes with a mixed coating of ruthenium and iridium are suitable for environmental wastewater treatment. Customers should, therefore, identify the specific coating material and the substrate of the electrode they need based on the working conditions of their current project.

• Geometrical factors

  Geometrical factors are the different shapes and sizes of electrodes. They affect the current distribution and mass transfer in an electrolytic cell. The geometrical factors also influence how electrolytes flow over the electrode surface.

  Customers should consider the available space for installation and the surface area or dimensions of the electrode. They should also consider the geometry of their existing electrode system. This ensures there are no compatibility issues and that performance is optimized.

• Tolerance

  Customers should consider the tolerance of the titanium MMO electrode in terms of current density, overpotential, and electrode surface area. These factors directly impact the efficiency of electrochemical reactions.
