The qualitative and quantitative evaluation of liberation of economic minerals and the
level of contamination of the process products by waste components were carried out
for the purpose of analysing the technology level and forecast its development directions.
Concentration of intergrown particles into a separate product for the purpose of
subsequent more efficient and selective liberation is one of the reserves for energy
saving in the grinding operations.
A pilot selective separator was tested in re-cleaning operations to compare with a
standard (conventional) separator. The tests that showed, that a separator with a
pulsed magnetic field is an efficient device that allows the realization of an intensive concentration
of a large amount of unliberated magnetic particles consisting of two phases
value minerals and gangue, into several products.
