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% Fe\(_\mathrm{total}\) and 3–35% of Fe\(_\mathrm{magn}\) 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 Fe\(_\mathrm{total}\) in the ore product reaches 1.18 times at the loss of 5.52%.
摘要文章介绍了使用磁力、重力和X射线辐射测量法进行粗颗粒分离，对库尔斯克磁异常区雅科夫列沃矿床铁矿石的可制备性进行的评估。详细研究涉及的材料粒度为（-100+25）毫米，含铁（总铁）25-45%，含铁（磁铁）3-35%，需要进行选矿。研究发现，通过 X 射线辐射测量法分离粗颗粒（-50+25）毫米，可以有效地将初始原料分离为矿石和污垢。当分析参数等于2时，矿石产品中铁的含量增加了1.18倍，损失率为5.52%。
