How to achieve quartz purification at a lower cost of PTMS Magnetic Separator separation
published date: 2022/9/6

electromagnetic separation

Dilute acid has a significant effect on the removal of iron and aluminum, while for the removal of titanium and chromium, sulfuric acid and aqua rega are used for acid leaching treatment. Usually, mixed acids composed of the above acids are used for acid leaching removal of impurity minerals. Various factors of acid leaching should be controlled according to the requirements of the final grade of quartz, as far as possible to reduce the concentration, temperature and amount of acid, in order to achieve a lower cost of PTMS magnetic separator separation quartz purification.

PTMS magnetic separator

The quartz sand ore in a certain area of Yunnan Province is mainly composed of quartz, accounting for 95-97%, silicic cements for 8-23%, and impurity minerals are mainly hematite and limonite, accounting for about 1-3%. The original concentrator adopts the process of sieving classification, dry magnetic separation, strong scrubbing with dosing and flotation. The final SiO2≥97.62%, Fe2O3≤0.24, Al2O3≤1.11%, the index is poor, which seriously affects the production index and economic benefits of the enterprise.

what is magnetic separation in science?

Generally, after scrubbing, desamming, PTMS magnetic separator and flotation, the purity of quartz sand can reach more than 99%, which basically meets the needs of industrial sand.
