Metals Processing


Metals Processing

Advanced techniques for metals have enabled many new products, such as lighter and more aerodynamic vehicles, and safer and more reliable medical devices. At the same time, rising environmental regulations remain key concerns for manufacturers. Ion exchange and chelating resins are a proven way to reduce water usage and waste impact. Ion exchange resins enable water recycling, and specialty chelating resins recover precious metals such as silver, gold, copper, and platinum group metals. Ion exchange treatment of effluents removes toxic metals, allowing safe disposal of wastewater.

  • Economical advantage

Metal Wire Cutting (EDM)

Electrical Discharge Machining (EDM) uses a thin metal wire as an electrode to generate intense thermal energy to cut through a metal work piece. EDM is ideal for precision cuts and is used to make automotive and aerospace parts and components, implantable medical devices, and small prototypes builds. Water is used as a coolant and to flush away eroded metal particles. Ion exchange technology is vital to reducing conductivity in the water and ensuring the process maintains high performance.

Metal Plating

Metal Plating

Metal plating is used to improve thermal resistance and reduce corrosion in airplanes and automobiles, increase conductivity in electronics, and increase biocompatibility in medical devices. The most common metals used are gold, silver, copper, nickel, and zinc. Large quantities of water are used in the procedure, and significant quantities of heavy-metal water wastes are formed. Jacobi’s metal chelating and ion exchange resins are sustainable solutions to help manufacturers reduce their cost and environmental impact. We can help you increase recycling and convert to closed-loop systems, minimizing release to the environment.

  • Gold and silver metals recovery using Jacobi’s SBA resins.
  • Reuse and recycle electroplating baths by metals removal using Jacobi’s SAC and SBA resins.
  • Recycle acidic pickling baths by removing zinc and iron complexes using Jacobi’s SBA resins.

Mixed bed (ready-to-use)

Removal of all ions from a water stream (salts and minerals) to lower conductivity.



Strong Based Anion

Strong base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a tertiary or quaternary ammonium group which removes anions in various processes. Resinex SBA comes in gel or macroporous type and is available in different bead sizes.


Chelating Resins

Specialist resins for ion exchange processes where there is a high presence of competing ions



WAC are polyacrylic, gel or macro ion exchange beads. They have the unique carboxylic acid functions.


Mixed Bed Resins

Composed of strong cationic and anionic ion exchangers based on a polystyrene-divinylbenzene matrix.


Strong Acidic Cation

Strong acidic cation resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a sulfuric group which attracts cations. Resinex SAC comes in gel or macroporous types and are available in several bead sizes to adapt to different applications.
