Method for recycling weakly magnetic iron ore from fine-fraction waste rock

The invention discloses a method for recycling weakly magnetic iron ore from fine-fraction barren rock, which comprises the following steps of: 1) screening 0-5mm barren rock with the iron grade of 15-18% and thrown out by dry pre-selection of a mine into two fraction ranges of 0-1mm and 1-5mm by us...
