  • step a) and/or step c) be carried out at a temperature of approximately 50°C.
  • the following description is in the context of a copper extraction plant.
  • the present invention is not confined to separating polonium from this valuable metal and is equally applicable to separating polonium from other valuable metals, such as nickel.
  • the prior art in its simplest form is a dust leaching process such as the process shown in Figure 1 and is a single step process carried out on a batch or continuous basis in a leaching tank.
  • the process includes forming a slurry of a smelting furnace dust of a copper extraction plant; a raffinate from a solvent extraction circuit of the copper extraction plant or water; and sulphuric acid.
  • the density of dust particles in the slurry is of the order of 120 g/L.
  • the concentration of sulphuric acid is approximately 100 g/L.
  • the pH of the second step is maintained at a value less than the pH of the first step.
  • the free sulphuric acid concentration be greater than 50 g/L and more preferably around 100 g/L so as to dissolve polonium and polonium compounds into solution.

Abstract

La présente invention concerne un procédé de lixiviation de la poussière en deux étapes. La première étape comporte un première lixiviation suivie d'une séparation solide/liquide. La phase 'liquide' de la séparation solide/liquide a une concentration relativement élevée d'un métal précieux (tel que du cuivre) et une concentration relativement faible principalement de polonium. La phase 'solide' de la séparation solide/liquide contient des métaux précieux (tels que du cuivre, de l'or et de l'argent) et du polonium et a une concentration relativement élevée de polonium comparé à la phase liquide. La phase 'solide' est transférée à la deuxième étape. La deuxième étape comporte une deuxième lixiviation suivie d'une séparation solide/liquide. La phase 'liquide' a une concentration relativement élevée de polonium et une faible concentration d'un métal précieux (tel que du cuivre). La phase 'solide' contient des métaux précieux (tels que du cuivre, de l'or et de l'argent) et du polonium et a une concentration relativement faible de polonium. La phase liquide de la première étape et les phases solide et liquide de la deuxième étape peuvent être utilisées de façon avantageuse dans d'autres étapes de traitement d'une usine d'affinage pour récupérer les métaux précieux.
