Magnetic separator

A mine originally used spiral chute and shaking table for rough separation of ore. Because of its low recovery rate, the mine accepted the PTMS recommendation to adopt PTMS vertical ring pulsating high gradient magnetic separator for technical transformation of the beneficiation process. After several times of transformation, the beneficiation process. The main advantages of the modified process are as follows:
(1) because the lower limit of particle size of PTMS magnetic separator can reach about 10 μm, so the magnetic separation tailings with hydraulic classifier classification can reduce the overflow flow, so that more fine ilmenite into the separation operation. After the reconstruction, the amount of mineral and metal lost in the overflow decreases from about 32% to about 17%.
(2) Because of the wide range of particle size of PTMS magnetic separation machine, the selected materials are no longer divided into coarse and fine grain levels, thus simplifying the processing process

PTMS magnetic separation

(3) PTMS magnetic separator to replace the spiral chute and shaking table after the operation recovery rate is greatly improved. PTMS magnetic separation machine, spiral chute and shaking table beneficiation index comparison results can be seen. Although after several years of mining, the grade of the ore is greatly reduced with the grade of the raw ore, the recovery rate of PTMS machine is 21. 99 and 32. 67 percentage points higher than that of the spiral chute and the shaking table respectively, which makes the amount of metal into the flotation operation increased from about 22% to about 48%.

what is magnetic separation method?

(4)The particle size composition of the feed ore in flotation operation is improved. Because PTMS magnetic separator for 0. 15 ~ 0. 02 mm particle size mineral recovery up to 85%, and this particle size is just the best range of flotation, so the flotation recovery from the past about 48% increased to 69%.
