The invention provides a method for recycling hematite combined tailings. The method comprises the steps of regrinding rough concentrates and then sorting the rough concentrates by using a weakly magnetic and strongly magneticreverse flotation process; and the method is characterized by comprising the following steps of feeding rough concentrates obtained by sorting hematite tailings into a ...
hematite iron recover
Hematite: A primary ore of iron and a pigment mineral. Historically, much of the hematite was not recovered and was sent to tailings piles. More efficient processing today allows more hematite to be recovered from the ore. The tailings can also be reprocessed to recover additional iron and reduce tailings price
Tailing From Hematite Mining
· Iron Recovery from Hematite Tailings by a Novel . During the processing of iron ores, a large quantity of lowgrade tailings containing abundant iron values in fine particle size range is produced. A novel HGMSCentrifuge process is proposed to recover iron values from a lowgrade hematite tailings.
How to generate value from tailings with reprocessing to ...
Oct 15, 2019 · With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a costeffective approach compared to processing material.
