Treatment of antimony mine drainage: challenges and

However, this process is more costly and iron oxide activity can be inhibited by plenty of sulfate in antimony mine drainage. In the presence of sulfate reducing bacteria, sulfate can be reduced to sulfide and form Sb(2)S(3) precipitates.

Treatment of antimony mine drainage: challenges and

It is found that iron oxides prepared by chemical methods present superior adsorption ability for Sb(III) and Sb(V). However, this process is more costly and iron oxide activity can be inhibited by plenty of sulfate in antimony mine drainage. In the presence of sulfate reducing bacteria, sulfate can be reduced to sulfide and form Sb 2 S 3 .

US3951786A - Oxidizing method in froth flotation of

An improved method in concentration of oxide ores and minerals by froth flotation process which comprises subjecting a pulp of mineral slurry to the combined action of a organic nitrogen compound with one or more NH 2 group and hypochlorite in a slightly acid pulp of mineral slurry. The decomposition of the NH 2 group provokes a highly oxidizing state in the mineral slurry, a state which can .

Biological and Bioelectrochemical Recovery of Critical and

 · Biogenesis of minerals such as magnetite (Fe 3 O 4), and greigite (Fe 3 S 4) in magnetotactic bacteria is a well orchestrated process, wherein the shape, size and composition of iron minerals are controlled by the cellular machinery, in particular the Mms6 protein . While in the case of many other biominerals, intracellular and extracellular .

Geochemical Factors Affecting the Behavior of Antimony

At moderately reducing conditions, antimony speciation is dominated by the hydrolytic species Sb(OH)3° (aq) at pH values from 2 to 12. The concentrations of antimony in soils and sediments are likely controlled by adsorption reactions, but very little is known about the adsorption/desorption behavior of Sb(V) or Sb(III). Antimony

Microbial Antimony Biogeochemistry: Enzymes, Regulation

Antimonate reduction. Antimonate reduction appears to be widespread in the environment, and it is prone to occur under anaerobic conditions ().It is known that Sb(V) can be abiotically reduced to Sb(III) by Fe(II)-containing minerals (56 – 58).A marine macroalga, Sargassum sp., was the first reported organism able to reduce Sb(V) in seawater ().In the treatment of leishmaniasis, several .
