Free Flow recently conducted treatability studies on industrial slag material from China. The criteria was stringent as China has their vrsion of a water leach test that is similar to the SPLP in the U.S
Typically the SPLP test is difficult to pass with a reagent added as most chemistries raise the pH to a level that induces leaching activity.The Free Flow chemistry however had no difficulty meeting the criteria for China. A 2.5% dose confirmed all metals well below the Chinese criteria.
