The customer requested to remove the metal impurities contained in the iron ore, which is as high as 65% iron.

Iron ore discharge grade reaches 65% (silica and alumina reduced from feed material increasing Fe content to over 60%)

Solutions:

The Iron ore is firstly crushed by the jaw crusher, and after crushing to a reasonable fineness, it is evenly sent to the ball mill through the elevator and feeder, and the ball mill crushes and grinds the ore. After the ball mill grinding, the ore fines enter the next process: classification. The spiral classifier washes and classifies the ore mixture by the principle that the specific gravity of solid particles is different and the speed of sedimentation in liquid is different.

When the washed and graded mineral mixture passes through the magnetic separator, the magnetic materials in the mixture are separated by magnetic and mechanical forces due to the different specific magnetization coefficients of various minerals. After the desired minerals are separated out, because they contain a lot of water, they must be concentrated by the initial concentration of the thickener, and then dried by the dryer to get the dry minerals.
