mixtures can be done on mixtures of magnetic and non-magnetic substances. Background to experiment Magnetic separation is one of the ways of separating heterogeneous solid mixtures. This is done by the use of a bar magnet. A bar magnet is an object made of certain materials which can attract metals like iron.
Secondly, the magnetic separation condition test shows that the lead and zinc content can be reduced to 0.32 % and 0.17 %, but the magnetic separation process alone cannot reach the standard. The use of the magnetic separation-flotation process to treat the pyrolysis slag can reduce the content of Pb and Zn to 0.14 % and 0.10 %.

Magnetic Separation 2.1 Introduction The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three main categories, namely diamagnetic, paramagnetic, and ferromagnetic.
The distinguishing feature of the magnetic separation is the presence of long-range, dipole-dipole interparticle magnetic forces that may lead to undesirable microparticle clustering (chaining or amorphous aggregation) and deterioration of the magnetic separation quality if left unchecked (Rosensweig, 2014; Williams et al., 2010).
