Production process

Our production process is multi-phased and the stages can be combined on a flexible basis depending on the properties of the materials delivered and the results of a detailed chemical analysis:

  • Mechanical preliminary treatment Separation from inert materials, homogenizing,
    grinding of the material
  • Thermal treatment Separation of volatile and combustible components. Depending on the characteristics of the feedstock and the desired final product we have the option to use fluidized bed or rotary kiln technology with direct or indirect firing equipment.
  • Wet-chemical processing Recovery of the different metals in the form of defined
    chemical compounds. Therefore, a wide range of different instruments for leaching operations, cleaning steps, precipitation, filtration and extraction is available.
  • Various purification processes Assuring the continuous high quality of the products
