2020-9-8 The flotation process is mainly used for the separation of fine-grained and particulate weakly magnetic iron ore, including two process flows of positive flotation and reverse flotation. Among them, the positive flotation process is suitable for quartz hematite ore without easy pumice gangue, and the reverse flotation process is suitable for ore with easy flotation gangue.

2015-5-9 During the process two conceptual flow sheets were also developed for the beneficiation of goethite iron ore fines. In the prsent work it was possible to enhance grade of iron to 63.35, 63.18, and 65.35 % from Jigging, Multi Gravity Separation (MGS) and Wet High Intensity Magnetic Separator (WHIMS) respectively.

2004-1-23 Iron ore fines varying in quantity from ore to ore are generated as a result. Ultrafines and slimes are difficult to concentrate by conventional methods such as gravity, flotation, magnetic, etc. and are either separated prior to the concentration and treated separately [5] , [6] , [7] , [8] or enriched by an alternative method such as selective flocculation [9] , [10] .
