However, the upgrading of ultrafine magnetite flotation was rarely addressed. Chipakwe et al. examined the effect of a polyacrylic acid-based grinding additive (GA) through flotation separation of magnetite from quartz (size fraction of − 106 + 38 µm) using an ether amine-based collector and indicated that using GA can reduce collector consumption 11.

This study aimed to investigate the potential of enrichment of rare-earth-bearing minerals in historic mine tailing using the froth flotation process. Characterization studies indicated that tailings contained 11,000 ppm of rare earth elements (REEs). The major mineral in the tailings was apatite at ~84%, which was associated with iron oxides (~16%). TESCAN's …

A considerable amount of ultrafine magnetite as the iron source will end up in the tailing dams since the magnetic separation process markedly drops as the particle size.

Iron concentration tailings contain many valuable minerals, including apatite, which is not currently being recovered despite its use to make fertilizers and chemicals. This article proposes a flotation circuit to recover apatite from tailings generated by mining in Chile, based on laboratory tests and using the "Split Factor" method. The iron tailings were characterized by …

The flotation process of vanadium–titanium magnetite tailings after one roughing and three sweepings can obtain the separation index of cobalt–sulfur concentrate, with a cobalt grade of 1.53% and cobalt recovery of …

This paper describes a study aiming at producing a magnetite pellet feed from a Sossego DAM copper tailing, which industrial copper flotation plant is in northern Brazil.

Also, the tailing particle contains a significant amount of Ca (23.52 wt.%) and P (12.58 wt.%). Source of Ca in the flotation tailing comes from phosphate or largely carbonate minerals like calcite and dolomite. Figure 6. XRD patterns of flotation concentrate (i.e. apatite conc.). Figure 9. SEM-EDS images of flotation tailing. 4. CONCLUSION ...
