26.11.2020· The present results indicated the feasibility of the electroflotation process for the recovery of fine and ultrafine iron ore particles using the biosurfactant extracted from Rhodoccocus opacus. The FTIR spectra showed characteristic functional groups of the biosurfactant in hematite after interacting, such as NH, CH 2, C=O, COO˗, PO 2 − .

The inhibitor of iron ore uses the sodium silicate, tannin and sodium lignosulfonate, and their inhibitory effect is the best when the pH value is 8-9. In terms of the ore properties of hematite ore, reverse flotation process is more advantageous than the positive flotation process. Because the collecting object of the reverse flotation process

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C

Mining organisms inhabiting iron ore deposits are implicated in biomineralization processes such as hematite, magnetite, and goethite formation as well as their oxidation–reduction, dissolution, and precipitation in mining environments. Similarly, gangue minerals such as silica, silicates, clays, calcite, alumina, and phosphates are often biogenically entrapped and encrusted in the hematite–magnetite
