Introduction
gold extraction with acid from waist
Products improvement
The Extraction of Gold from Ewaste by The leached solution is separated from the waste and then gold, using extraction technique with solvent recovery and then organic phase containing gold and 2 molar or more choleric acid as detergent solution, is extracted from other impurities. Oxalic acid is used to remove residue and extract gold from organic extractor charged with gold.Extraction of GoldIt
