Since the minerals formed by these bacteria included highly crystalline Fe(III) minerals that are hardly reducible by Fe(III)-reducing bacteria, stimulation of arsenic immobilization by Fe(II)-oxidizing bacteria can potentially support water treatment systems or even be applied as an effective remediation strategy.

Antimony is sometimes found as an element, but normally it is found as stibnite, an antimony sulfide mineral. Stibnite is the main ore of antimony. China is the biggest maker of antimony; it .
For each reaction in problem 13, identify the oxidizing agent and reducing agent. 15. Write half-reactions for the oxidation and reduction process for each of the following.
The quantity of antimony in an ore can be determined by an oxidation-reduction titration with an oxidizing agent. The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony is in the form Sb3 (aq).
As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
sumption of antimony. antimony oxides are used as white pigments the industrial mineral processing of a typical Chinese stibnite ore in paints.7% Sb is put to a Table 2 combined treatment by hand-sorting.
Antimony and As are both chalcophilic elements that often cooccur in association with sulfide minerals around hydrothermal ore deposits. Ecosystems surrounding mining and smelting operations can therefore become contaminated due to oxidative dissolution of Sb- and As-sulfides in sulfidic mine tailings ( 5 – 8 ).
Oct 03, 2010· Antimony is found naturally in a number of minerals including stibnite. Stibnite typically contains 5% of Sb2S3. Antimony can be obtained by reducing Sb2S3 with scrap iron.

Flotation study on lowgrade antimony ore of qilla abdullah antimony ores need processing for an increase in metallic grade as well as reduction of 2Government .
Under reducing conditions, antimony concentrations may be limited by the solubility of Sb(III) sulfides, such as stibnite (Sb 2 S 3 ). Although cobalt can exist in the +2 and +3 oxidation states, Co(II) is the stable valence state in water
The antimony mineral resources of China mainly consist of stibnite, antimony-gold ore, and jamesonite, which accounts for 52%, 15%, and 25% of antimony production in 2010. A by-product from lead smelting—antimonial dust, which contains antimony, lead, bismuth, copper, arsenic, silver, etc.—is also an important secondary resource of antimony in China, which contributes 8% to Chinese antimony .

Antimony enters the environment during the mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations of antimony Although part of the slag is frequently reused in the furnaces to reduce volatilization losses (Anderson, 2012 Anderson, C.G. 2012.
The process also has application as an antimony recovery process for antimony mines. The process has been extensively tested, including a $4.5m 34 day pilot plant operation on Tampakan concentrate, successfully reducing the arsenic content from 1.1% to 0.1%.
The mineral processing of antimony. Originally antimony was mined and hand sorted to effect concentration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application. However, in recent years, many other unit operations are used in the mineral processing of antimony.
