Definitions

  • said method comprises a step of drying and/or heat treatment of the solid phase resulting from the oxidation/neutralisation step enabling iron oxides and/or iron oxyhydroxides to be obtained.
  • FIG. 2 is a schematic diagram depicting the steps of the method according to one embodiment.
  • a step of separating the solid/liquid phases generated is then carried out, which may be accompanied by washing of the solid phase.
  • the aim of this washing is to eliminate as much as possible the salts still present in the solid phase where they were not solubilised in the attrition and dilution step.
  • the solid phase is separated from the wash water.
  • the oxidation reaction is carried out by means of a liquid oxidant such as hydrogen peroxide or a gaseous oxidant such as air or oxygen at a pH maintained between 2.5 and 5 by means of a basic solution such as a soda solution or similar.
  • a liquid oxidant such as hydrogen peroxide or a gaseous oxidant such as air or oxygen
  • a basic solution such as a soda solution or similar.
  • the ratio R 4 (dry matter in kg)/(reaction volume in litres) is substantially between 0.05 and 0.15.
