process streams are by precipitation as arsenic(III) sulfide, calcium arsenate, or ferric arsenate, but it has been shown that all of these materials are unstable under certain conditions and therefore not suitable for direct disposal to uncontained
The process of recovering arsenic from its ores is a common one used with metals. The ore is first roasted (heated in air) to chemically convert arsenic sulfide to arsenic oxide. The arsenic oxide is then heated with charcoal (pure carbon ).
Arsenic is one of the components of a large number of compounds generated by human activities (precious metals mining, pharmaceutical manufacturing, wood processing, glassmaking industry, electronics industry, chemical weapons etc.) .
Arsenic has no odor and is almost tasteless. Arsenic and its compounds have a variety of commercial uses. Manufacturers use arsenic to make other metals, glass, electronic components, and wood preservatives.
Arsenic is used industrially as an alloying agent, as well as in the processing of glass, pigments, textiles, paper, metal adhesives, wood preservatives and ammunition. Arsenic is also used in the hide tanning process and, to a limited extent, in pesticides, feed additives and pharmaceuticals.
After the arsenic removal process, the treated water has a low arsenic concentration, typically around 1-3 mg/L. If an even lower arsenic concentration is required, a polishing step with enhanced arsenic removal can be included.

Arsenic Arsenic appears in three allotropic forms: yellow, black and grey; the stable form is a silver-gray, brittle crystalline solid. It tarnishes rapidly in air, and at high temperatures burns forming a white cloud of arsenic trioxide.
Other arsenic compounds are applied as a wood preservative, in glass processing, in chemical industries, or in semiconductor technique together with gallium and indium. Dutch painters applied arsenic as a yellow pigment.
SORAS is a simple arsenic removal process applied at level with locally available resources. However, the arsenic removal efficiency is limited to approx. 50 - 70 % and hence, raw water up to 100 - 150 m g/L can be treated with this low cost method.
Arsenic is a chemical substance, which is released from the Earth's crust via natural processes and from certain human activities. It can exist in inorganic or organic form, inorganic arsenic being generally considered more toxic.

Chemical oxidation is used in water treatment to aid in the removal of inorganic con- taminants such as iron (Fe 2+), manganese (Mn ), and arsenic (As3+) to improve re- movals of particles by coagulation or to destroy taste- and odor-causing compounds.
