PTMS MAGNETIC SEPARATOR

what is magnetic separation used for ？

1. The effect of magnetic declination on magnetic separation If the magnetic declination is small (ie, biased to the ore end), the tailing grade will be reduced, but the effect on the concentrate grade will be small; if the magnetic declination is too small (<5) °), the discharge of concentrate is difficult, the grade of tailings rises, the tailings appear to run black, and the ore end is easy to fall. If the magnetic declination is increased (ie, biased to the unloading end), the tailings grade is slightly increased, and the effect on the concentrate grade is not obvious; if the magnetic declination is too large (>20°), the tailing grade is increased, and the tailings are increased. There is a black phenomenon and it is difficult to unload the concentrate. The proper magnetic declination is to ensure normal unloading, and to ensure that the tailings do not run black.

2. Effect of slurry concentration on magnetic separation If the concentration of pulp is too large, resulting in too high sorting concentration, it will seriously affect the quality of concentrate. Because the concentrate particles are easily covered by finer gangue particles and the package is not separated at this time, they are selected together to lower the grade. If the concentration of the slurry is too small, the concentration will be too low, and the flow rate will increase. The selection will shorten the pairing, so that some small magnetic particles that would have been available should fall into the tailings to increase the grade of the tailings and cause losses. and so. The maximum concentration of the feed slurry should not exceed 35%, and is generally controlled at about 30%.
