This arsenic-driven gold pump explains how these iron sulfides can massively capture and then release gold, so controlling ore deposit formation and distribution. For example, an agitated tank can be used to wash the carbon. More recent work has focused on methylated arsenic metabolites in humans or exposure to inorganic arsenic during early life, and has provided the information to show potential links between arsenic and carcinogenesis.
Operating Cost is Drastically Lower Compared to Alternative Technologies. No other oxidants such as hydrogen peroxide or ozone are typically required.
They were exposed in early childhood to high levels of arsenic through the drinking-water. This concentration could be further increased by raising the stripping process temperature, duration and arsenic load on activated carbon. Required oxygen 112 for the reaction can be achieved by the use of air, oxygen-enriched air or industrial-pure oxygen gas and the non-reacted portion of the gas may be vented out as off-gas 116.
How to Remove Arsenic from Drinking Water The presence of arsenic in the waste waters from the processing of gold bearing sulphides presents serious problems which are not easily overcome by simple precipitation techniques.
Ettringite sludge is easily dewatered, and may be reused in the process as seed sludge to reduce the quantity of coagulant required. Due to the high temperature applied in this alternative method and the presence of at least stoichiometric amounts of ferric iron, arsenic adsorption to the carbon additive is believed to be minimal, at best, and no washing step is commonly required.
Braz J Chem Eng 31:183—193• The authors of this paper have been involved on many mining projects, mostly in the Western United States, where elevated arsenic content impacted the development of mineral deposits, or created a potential for environmental problems. Aftermarket parts, media replacement and technical support.

The remaining second treated stream 144 can be recycled back to the arsenic-loaded carbon additive washing stage 524 and re-used, sent back to the off-gas scrubbing stage not shownor bled out Arsenic removal from gold processing waste waters may require an arsenic polishing step to remove any remaining arsenic before bleed of the treated stream.
The process produces a net reduction in total dissolved solids TDS. J Integr Environ Sci 6:295—316• The epidemiological evidence from inhaled arsenic mixtures permits the evaluation of the carcinogenicity that is related to inorganic arsenic compounds.
