Leaching and Adsorption of Gold from LapeSumbawa Rocks
Jan 01, 2015#0183;#32;At the pH lt;, the chlorine gas was formed. HClO was formed at pH of to while ClO ions was formed at pHgt; The gold extracted was increased as the pH was lowered at certain value6,7,8. Gold is oxidized by HClO to form [AuCl4] complexes in the chloride solution. The extraction of gold depends on the reaction time7.
