Arsenic-containing waste materials comprising water-soluble arsenic salts are processed to a product which comprises water-insoluble arsenic salts by reacting the same in an aqueous system with sulfuric acid and calcium hydroxide in the presence of sulfate ions and ferrous and/or ferric ions, and thereafter curing the system to solid form.

The process can be practiced with conventional waste materials without preliminary special processing, and provides a product which can be easily handled and is amenable to secure landfill disposal.
