Abstract

The problem of treatment of the dump of Khovu-Aksy with conversion of arsenic into a storable nontoxic sulfide form was studied. The optimum conditions were developed: annealing of sludge in a mixture with sodium carbonate, water leaching from the cake stub, and precipitation of arsenic in sulfide form from solution.

Keywords
