From Basic Idea to Running Industrial Operation

Process Development and Plant Design

From Raw Material to Process


Process Development for production of Mineral Fertilisers.

Raw Materials:

  • Mined Raw Salt from marine Evaporites (Carnallite, Sylvinite, mixed Salts)
  • Natural brine from recent Salt Lakes
  • Seawater, brines and bittern from sea salt production
  • Solution mining brines (solution mining of rock salt, Sylvinite, carnallite, selective hot solution mining or cold solution mining)
  • Industrial waste brines and solid waste

Mechanical Basic Operations:

  • Comminution and Classification
  • Leaching and dissolving
  • Precipitation of poorly soluble substances
  • Flotation
  • Decomposition and conversion of double salts
  • Fractional crystallisation of simple and complex salts, (Carnallite, Kainite, Glaserite, Polyhalite Schoenite) by solar evaporation or industrial evaporation
  • Solid / Liquid separation by thickening, sedimentation, filtration
  • Drying
  • Precipitation of basic compounds (Hydroxides, Carbonates, Oxides) with caustic reactants
  • Storage of thermal energy by use of latent heat (phase change materials) or by use of sensible heat of large volumes of salt solutions
  • Brine purification and use of purification effluents

Products:

  • Potassium chloride and potassium sulphate in fertiliser grade or industrial (Sylvine, MOP, KCl98/99, SOP)
  • Sulphatic double salts (Schoenite, Leonite, Langbeinite, Kainite, Glaserite), Potash-Magnesia
  • Basic magnesia compounds (MDH, CCM, DBM, precipitated magnesia-carbonates)
  • Magnesium salts, magnesium chloride (Bischofite), magnesium sulphate (Epsom Salt, Kieserite)
  • Sodium chloride in food grade, animal food grade or industrial grade
