“…In the direct mechanisms, the bacteria catalyze the reaction through an enzymatic attack that involves physical contact between the bacteria and the mineral ore through the extracellular polymeric substances (EPS) (Huang and Li, 2014). The indirect mechanisms take place by means of chemical reactions in which the ferric ions are reduced to ferrous iron by oxidizing the metal sulfide and leaching it in its soluble form (Ciftci and Atik, 2017). The cooperative mechanisms involve the dissolution of sulfur colloids, sulfur intermediates, and mineral fragments by planktonic cells (Rawlings, 2002;Tributsch, 2001).…”

The possibility of sorption extraction of nickel from leaching solutions of oxidized nickel ores of the Buruktal deposit is considered. Ionite Lewatit TP220 with bis-picolylamine functional groups is effective for nickel recovery against the background of high iron contents. Lewatit TP220 is mechanically strong enough for use in the resin-in-pulp process. Nickel sorption with satisfactory performance occurs both in the variant of sorption leaching and extraction from clarified solutions. At sorption from the pulp, the capacity for nickel was 5.44 mg/g, for iron, 25.17 mg/g. The use of 20% sulfuric acid provides quantitative nickel desorption. To obtain a higher quality nickel-containing product, it is recommended to additionally purify the resulting eluates from iron.
