Quartz sand iron removal scheme

PTMS magnetic separation

Which ore is used in magnetic separation method?

Quartz deposits are widely distributed throughout the country and around the world.

1. Natural quartz sand: mainly marine, sand and lacustrine sand formed by the Tertiary and Quaternary. The composition of quartz sand varies greatly from place to place, and the SiO2 content ranges from 89-98%.

2. Quartz sandstone: mainly quartz sandstone formed by the Sinian and Devonian sediments. Due to the different regions and metallogenic environments, the composition of quartz sandstone is also quite different, and the SiO2 content ranges from 95-98%.

3. Quartzite and vein quartz: Quartzite is mainly formed in the Proterozoic and Sinian. The vein quartz is mainly formed in Archean. The SiO2 content in quartzite is generally 98-99.5%, and the SiO2 content in vein quartzite is generally greater than 99. %

Quartz sand often contains more or less iron elements, such as goethite, hematite, limonite, ilmenite, pyrrhotite, etc. The presence of these iron impurities greatly reduces the use value of quartz sand. Influencing the quality of the product, in order to improve the grade of quartz sand in the actual production process, it is necessary to reduce the content of iron. Commonly used quartz sand removal methods include mechanical scrubbing, magnetic separation, flotation, ultrasonic cleaning, acid leaching, etc. The process, choose the mineral processing technology suitable for your own minerals to achieve the best beneficiation effect.

Magnetic separation iron remover is the most commonly used beneficiation method, which separates magnetic minerals from non-magnetic minerals. The beneficiation process is divided into dry and wet methods. The wet magnetic separation can remove the red including the continuum particles. Weak magnetic impurity minerals such as iron ore, limonite and biotite.
