Abstract
The article contains the results of a study of the specific magnetic susceptibility of primary concentrates of Siberian iron ore deposits and its dependence on the magnetic fi eld of the separator. The experiments (laboratory separation, magnetic measurements) were performed on the class size of –0.07 mm. Study of ore subjected to seven deposits, four of which are magnetite and three – lightly oxidized, due to their content of martite, hematite and limonite from 3% to 6%. The middlings of magnetite ore have the largest values of magnetic susceptibility, the middlings of lightly oxidized ores have the less value. But the fields of maximum specific susceptibility of lightly oxidized ore samples are higher than the maximum specific susceptibility of magnetite middlings samples. The experiments have shown that the values of specific magnetic susceptibility of primary concentrates are proportional to the content of magnetite iron in them.
