- 1 - Abstract A process is described for concentrating a mixed martite/hematite ore using wet high intensity magnetic separators, such as Jones Separators. A slurry of the mixed ore is first passed through a primary grooved-plate high intensity wet magnetic separator having plate gaps of 3 mm to 15 mm, groove widths 1 to 3 times the gap distance and a magnetic intensity of 2000 to 10000 gauss, thereby separating the slurry into a first magnetic stream, a first middling stream and a first non-magnetic stream. This first magnetic stream is collected as product and the first middling stream and first non-magnetic stream are combined to become a feed slurry through a secondary grooved plate high intensity wet magnetic separator having plate gaps of 1 mm to 3 mm, groove widths of less than about 4 mm and a magnetic intensity of about 5000 to 15000 gauss, thereby again separating the slurry into a second magnetic stream, a second middling stream and a second non-magnetic stream. The second magnetic stream is also collected as product.
