PURPOSE: a kind of to purify containing heavy-metal contaminated soil and due to effectively keeping soil in scattering process by cost-effectively purification soil and returning nuisanceless soil to initial position. ;CONSTITUTION: wet classification processing and the classification solo of heavy metal pollution are due to scattering into coarse particales heavy metal free and particulate and heavy metal (S120). Magnetic separation process separation classification micro particle enters the magnetic flux density (S130) of magnetic mineral and non magnetic ore permanent magnet separator 10000-15000 Gausses. Filtering process segregating foreign objects are sieved before polluted soil 1-3mm using the wet classification processing (S110) of sieve. ;The 2012 of copyright KIPO submissions
