The PTMS MAGNETIC SEPARATOR purification process of powder quartz sand ore generally adopts the process of scrubbing and removing sludge-grading-magnetic separation-flotation-pickling. Classification: Due to the brittleness of the powder quartz itself and the mechanical force of grinding and denfoliation, the iron and clay materials attached to its surface are peeled off, and need to be graded to separate the target mineral and impurity mineral.
Scrub and remove sludge: scrub the quartz sand to remove the surface clay, mud impurities and film iron. Magnetic separation: grading PTMS MAGNETIC SEPARATOR to remove magnetic minerals. Flotation: nonmagnetic products into the flotation machine for flotation to remove impurity minerals such as feldspar and mica. Because of the relatively few impurities in the powder quartz, the use of reverse flotation is more conducive to reduce the amount of collector and foaming agent.
Acid washing: The separation of quartz from feldspar is mainly under acidic conditions, and sodium sulfonate and amine are usually used as traps. Flotation products after high temperature acid immersion, the acid immersion washing products are calcined to purify the powder quartz, PTMS MAGNETIC SEPARATOR iron removal.
