Abstract
The article presents evaluation of preparability of iron ore from Yakovlevo deposit, Kursk Magnetic Anomaly, using magnetic, gravity and X-ray radiometric methods of coarse particle separation. The detailed study involved a material with particle size of - 100 + 25 mm, containing 25-45% Fetotal and 3-35% of Femagn and requiring dressing. It is found that effective separation of the initial feedstock into ore and dirt is ensured by the X-ray radiometric method of separation of coarse particles - 50 + 25 mm in size. At the analytical parameter equal to 2, the increase in the content of Fetotal in the ore product reaches 1.18 times at the loss of 5.52%.
