How does PTMS magnetic separator correct problems in the processing of potash albspar ore
published date: 2021/5/12

Magnetic separation process

A concentrator is located in the potash albite ore area. This mine is to recover the resources in the magnetic separation tailings (containing about 12% magnetic minerals), and a ore dressing production line has been built in the initial stage. The process classifying the magnetic tailings into coarse grade, fine grade and overflow. The coarse grade is combined with fine grade after roughing and grinding by spiral chute, and the residual strong magnetic material is removed by low intensity magnetic separator, and then the final titanium concentrate is obtained through gravity separation and flotation by shaking table. PTMS machines can remove iron (Fe2O3) inside.

PTMS MAGNETIC SEPARATOR

The beneficiation process is modified by PTMS to solve the following main problems:
(1) Because the classification efficiency of hydraulic classification equipment is not high, about 30% of the loss is caused in the classification overflow. PTMS magnetic separator can remove the iron inside (Fe2O3).
(2) the separation granularity of the spiral chute and shaking table lower limit is only 30 microns, recovery of fine ilmenite in ascension to improve the cause of the spiral chute homework only about 59%, recovery of shaking table work effectively adjust recovery rate was only 47%, heavy parts (including the classification, spiral chute and shaking table) to enhance the comprehensive recovery.

what is magnetic separation in chemistry?

(3)Mineral flotation is positive flotation, and the spiral chute and shaking table can not recover fine minerals, so that the flotation of the ore feeding granularity is coarser, at the same time the mineral density is larger (4.7 ~ 4.8 g /cm3), so the flotation of minerals is easy to sink groove, resulting in low flotation recovery. After PTMS adjustment, the above situation has been improved to varying degrees. PTMS magnetic separator can remove the iron inside (Fe2O3).
