Claims (5)

1. Jordrensningsfremgangsmåde, hvor, et forbehandlingstrin med iblanding af et dehydreringsmiddel i jord (A, B, C, D, E, F) for reduktion af vandindholdet i jorden (A, B, C, D, E, F) til 10 vægt-% eller mindre udføres; et tørklassifikationstrin udføres for at klassificere jorden, hvis vandindhold er reduceret til 10 vægt-% eller mindre ved forbehandlingstrinnet, til grus, grov jord, og fin jord, under betingelser hvor et klassifikationspunkt for grusset og den grove jord er sat til 2 mm og et klassifikationspunkt for den grove jord og den fine jord af jorden i en partikelstørrelsesklasse på mindre end 2 mm er sat til 75 pm til 150 pm, og efterfølgende, et magnetisk adskillelsestrin til adskillelse og fjernelse af en forurening, som er chrom, arsen, fluor, bly, zink, kobber eller olie i jorden i partikelstørrelsesklassen på mindre end 2 mm, som magnetisk tiltrukket materiale, udføres.
2. Jordrensningsfremgangsmåde ifølge krav 1, hvor én afjorden, som er blevet underkastet forbehandlingstrinnet, og jorden, som er blevet underkastet det magnetiske adskillelsestrin, underkastes en tørformalingsproces.
3. Jordrensningsfremgangsmåde ifølge krav 1 eller 2, hvor én afjorden, som har været underkastet forbehandlingstrinnet, og jorden, som har været underkastet det magnetiske adskillelsestrin, underkastes en gravitationskoncentrationsproces.
4. Jordrensningsfremgangsmåde ifølge ethvert af kravene 1 til 3, hvor det magnetiske adskillelsestrin udføres i adskillige magnetiske adskillelsestrin, idet en magnet med højere magnetkraft anvendes i det senere udførte magnetiske adskillelsestrin, og det senere magnetiske adskillelsestrin anvendes på magnetisk ikke-tiltrukket materiale adskilt i det forudgående magnetiske adskillelsestrin.
5. Jordrensningsfremgangsmåde ifølge ethvert af kravene 1 til 4, hvor der som dehydreringsmiddel anvendes én af brændt kalk, gips og cement.
