| Abstract: | An useful method on extracting palladium from serpentine, and the experiment on the condition of extracting palladium from serpentine and the reduction of extraction were studied. Using di-(2-ethylhexyl)-dithiophosphoric acid (D 2EHDTPA) as the extractant in hydrochloric acid medium, the pH of the extracting liquid is 1 and the extracting time is 30 min, the recovery of palladium reached 98% determined by spectrophotometry. |
