黑色冶金工业的发展决定着愈益广泛地开采細粒嵌布貧磁鉄矿石和氧化鉄矿石。这些矿石必須經过細磨和富集。近年来,在处理量方面急剧地增长的主要是磁鉄矿石。要增加細粒精矿产量,不仅要求改善所采用的选矿方法、工艺流程和設备,而且要求研究新的、高生产率的选矿过程和机器。这些过程和机器也适合于有效地处理貧氧化矿石。細
The development of the black metallurgical industry dictates the increasingly widespread exploitation of fine-grained lean magnetite ores and ores of ores. These ores must be finely ground and enriched. In recent years, magnetite ores have been the major contributors to the dramatic increase in throughput. Increasing the production of fine-grained concentrates requires not only improvement of the beneficiation methods, processes and equipment used, but also the study of new and highly productive beneficiation processes and machinery. These processes and machines are also suitable for effectively treating lean, oxidized ores. fine
