Metals Plating Industry Products

Large amounts of water are used in the plating processes to make-up treatment baths and to rinse away residual salts, acids or alkalis from treated parts. Typically, after each step of the process, the material is rinsed with water which is conveniently recycled after demineralization with special ion exchange resins. Ion exchange resins and synthetic adsorbents can be used in the metal plating industry even to remove impurities from pickling and plating liquors, so extending their lifetime. Treatment of effluents removes toxic metals, allowing safe disposal of the waste liquor.

Ion exchange applications in the metals plating industry:

  • Acid retardation

  • Aluminium, iron and copper sulphate from sulphuric acid

  • Iron, nickel and chrome salts from nitric/hydrofluoric acid pickling baths

  • Purification of phosphoric and chromic acid pickling baths

  • Purification of nickel sulphate baths

  • Iron removal from hydrochloric acid pickling baths

  • Recovery of precious metals

  • Treatment of waste effluent
