Abstract

The influence of coarseness of magnetite is examined in iron concentrates after wet sieving analysis. The test concentrates are the products of Olkon, Karelskiy Okatysh and Stoilensky GOKs. It is shown that magnetic susceptibility of the concentrates gradually reduces with the decreasing size of magnetite particles in the material \(<50~\mu\)m and assumes the minimal values in the sieve residue \(<8~\mu\)m.
