Arsenic - Wikipedia

Under reducing conditions, H 3 AsO 4 is predominant at pH 2–9. Oxidation and reduction affects the migration of arsenic in subsurface environments. Arsenite is the most stable soluble form of arsenic in reducing environments and arsenate, which is less mobile than arsenite, is dominant in oxidizing environments at neutral pH.

How Antimony is Processed by Flotation

The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Antimony - Sciencemadness Wiki

Antimony pentoxide (Sb 4 O 10) cannot form by burning the element in open air, and is obtained by oxidizing antimony with concentrated nitric acid. Antimony also forms a mixed-valence oxide, antimony tetroxide (Sb 2 O 4), which features both Sb(III) and Sb(V).

Antimony - Simple English Wikipedia, the free encyclopedia

Antimony is not common. It is found about as often as thallium.It is quite easy to get, though and is in many minerals.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 makes 84% of all antimony.
