°C, a method for the separation of As in the form of sodium arsenate salt from the arsenic-rich leachate via cooling crystallization was established, and the reaction medium could be fully recycled... crystals were obtained and the crystallization extent was 88.9% (calculated on the basis of Na3AsO4). According to the redox potential, sodium arsenate was reduced into trivalent arsenic salt by SO2 gas......
