Quartz, the main mineral in quartz sand, is a diamagnetic substance that cannot be magnetized in a magnetic field. The impurity minerals containing iron in quartz sand: hematite, limonite, magnetite, goethite, etc., are mostly magnetic substances that can be magnetized in the magnetic field. The PTMS MAGNETIC SEPARATOR process utilizes this property difference to remove these iron-containing impurity minerals from quartz sand by magnetic separation.
In order to achieve the purpose of removing iron minerals and separating magnetic minerals from non-magnetic minerals, the magnetic force acting on magnetic minerals must meet the following conditions: The magnetic force acting on magnetic ore particles is greater than the combined force of all mechanical forces acting on magnetic ore particles. PTMS MAGNETIC SEPARATOR is divided into dry separation and wet separation.
Taking quartz sand ore production PTMS MAGNETIC SEPARATOR process as an example, the two processes of dry separation and wet separation are compared. It is found that the wet high intensity magnetic separation has the defects of high power consumption, easy media wear, large production water consumption and high operation and maintenance costs. The dry magnetic separation process is convenient to operate, and the operation and maintenance cost is lower than that of the wet type.
