However, for the arsenic removal process to be considered in arsenopyrite processing, it must not negatively impact the gold recovery in the subsequent thiosulfate leaching stage. Contrary to what was achieved for arsenic, the preceding stage of arsenic dissolution with oxalic acid, significantly decreased the gold extraction, from 81% to 32% compared to the case in which As removal is not applied ( Fig. 9 ).
