• Description:
  This report describes a study to test the effectiveness of using thiourea and thioacetamide to precipitate metals from wastewater and metallurgical process streams using two chloride leach washes and a sulfuric acid wash. Thiourea did not precipitate arsenic, whereas thioacetamide did precipitate it as a sulfide. It was found that most metals could be removed within the 96 to 99 pct range.
