Biogenetic iron oxide minerals from iron corrosion by iron-oxidizing bacteria may prove promising for antimony adsorption, while the micro-environment generated from …

Antimony can be attenuated by ochreous sediments composed of schwertmannite (Manaka et al. 2007), Fe and Mn oxides Asaoka et al. 2012), but also by …

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

) is an abundant antimony bearing mineral and thus it is the main source for the production of pure antimony trioxide and/or metallic antimony. The conventional technology for the production of metallic antimony from stibnite concentrates is primarily by oxidizing roasting to convert the stibnite into volatile antimony oxide (Sb 2 O 3

Big Creek Road. KeIIogg, Idaho 83837. 208-7 83- 1 2rr. FAX 208-783-121I EXT, 202. Abstract. Antimony has been utilized by mankind for thousands of. years. However, due to recent environnental ...

10%Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. A new pyrometallurgical process for producing antimony white from the antimonial dust is reported. The process mainly consists of three steps, which are reduction smelting, alkaline refining, and blowing oxidation.

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 ...

Dispersion of antimony from oxidizing ore deposits* ... Sulfide and sulfosalt minerals mostly form deep in the Earth at high temperatures and under compara-tively reducing conditions. They remain stable as long as they are protected from oxygen but, with few ... eral process has a very important consequence with respect to solubility phenomena ...

Antimony Mineral Processing - Know More. Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity separation This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance...

The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation.

Treatment of antimony (Sb) mine drainage is generally regarded as a priority issue for regulatory authorities. In the study synergetic removal of Sb(V) from wastewater using cheap scrap iron inoculated with iron-oxidizing bacteria (IOB) and sulfate-reducing bacteria (SRB) was proposed.
