This is a type of gravity separation Magnetic Separation This involves the use of magnetic properties of either the ore or the gangue to separate them The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller The magnetic ore remains on the belt and the gangue falls off the belt
This results from the high speed sequence of the alternate polarities of the magnet pulley From the ECS side the higher the frequency of the variable magnetic field and the larger the size and energy of the permanent magnet blocks mounted on the head pulley magnet the more performing the ECS separation
·Magnetic solid phase extraction MSPE is widely employed in glycoproteomics because of its simple operation short adsorption and desorption time low cost and ecological friendliness [24] As the core of MSPE technology magnetic adsorbents possess the ability of rapid separation of target analytes which benefiting from the excellent magnetic
