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 retaining suitable sulphur contents for smelting operations.

This implies that concentrates can undergo an arsenic removal pre-treatment and output an arsenic depleted mineral concentrate acceptable for traditional base metal smelters without the penalties usually imposed to complex concentrates and a stable insoluble arsenical glass product.

DST currently displays its arsenical glass at its Montreal headquarters, where a salt water fish tank is lined with arsenical glass and the fish continue to thrive.
