Development of Arsenic Removal Technology from Drinking,

At the global scale, drinking arsenic-contaminated groundwater is the most common way for people exposed to arsenic. A number of developing countries have serious arsenic contamination. And thus, developing technologies that could remove arsenic from drinking water has become a major focus ofarsenic removal technology - MEL Chemicals,MEL Chemicals in collaboration with WBD have tested Isolux arsenic removal technology at the Beijing Normal University in order to validate the claims made about the,Arsenic Stabilisation - dundeetechnologies,Arsenic Removal. DST has developed solutions for the removal of arsenic contained in mineral concentrates. The removal of arsenic, presented in the form of arsenopyrite or cobaltite, is done using a thermal decomposition in an inert environment in combination with stabilization of arsenic by vitrification. The arsenic content in the concentrate can be reduced by >95% , with no gold/cobalt losses, while
