The structure of ZH wet high intensity magnetic separators mainly contain one sieve to screen coarse residue and three magnetic separation disks. The sieve in front of the first separation disk can block the residue in the slurry. With multi-cells induction magnetic media whose intensity as high as **4 T, and corresponding different (or respective) media parameter of three disks, a multi magnetic induction field are formed, which is able to sector-by-sector separate the complex minerals with high and low magnetism, large and small particle size, extremely enhance the ability to capture target minerals especially those with small particle size.
