Chrome ore dressing method

Of depleted of chromium ore beneficiation, we have used jigger, shaker, spiral concentrator, centrifugal concentrator and belt sorting through the chute around the depleted chromium ore _{_{(Cr 2 O 3 <20%}} ), but also a force sufficiently washed with water selected from The pipe was selected to pass the shaker in the mine. Dry strong magnetic separation, wet strong magnetic separation, flotation and various chemical beneficiation methods were studied in the laboratory. However, in the production technology, the re-election method is adopted, and the selective mining method such as strong magnetic separation and flotation method in some mines is still immature.

Since 1967, China has built five small ore dressing plants in Zunhua, Beijing, Miyun, Shangnan, Inner Mongolia, Sauran, Inner Mongolia, and Saltohai, Xinjiang, with re-election and the first three with the end of mining. Sustained production. The existing Solon Mountain plant was built in 1985. The designed scale has an annual output of 3,000-4,000 tons of concentrate powder, 25% of the ore grade, 41% of the concentrate after re-election, but the grade of tailings is 10%. In 1986, it was put into production for the strong magnetic separation process.

The following picture shows the flow chart of the jigging-shake selection of the Erji chrome ore in Gansu.
