| description | In recent years, the properties of the ore mined in the Anqian area have changed greatly. In order to provide a basis for the formulation of the ore beneficiation process, it is necessary to carry out detailed process mineralogical research. In this paper, with the help of optical microscope, chemical analysis, X-ray diffraction and other analysis and detection methods, a comprehensive and systematic study on the chemical composition, mineral composition, dissemination particle size and inlay characteristics of the ore samples in the Anqian area was carried out. Research results show that the iron grade in the ore is 29.25%, and the main iron-bearing minerals are magnetite, hematite, limonite, and pyrite. The magnetite content is 31.65% and the hematite content is 6.53%. Iron ore type iron ore; gangue is mainly quartz, with a content of 45.44%, followed by hornblende. The automorphic crystal structure is more common in hematite in the ore, and the semi-automorphic crystal structure is more common in the magnetite. Individual magnetite is an alternate structure between two or more minerals. The particle size of magnetite and hematite is uneven, and the multi-stage grinding and multi-stage magnetic separation process can be selected. |
