Processing of high purity gold from scraps using

An improved process was developed to produce gold with purity > 99 9998 > 5 N from gold scraps using dibutyl carbitol DBC as an extractant The extraction of gold into DBC was optimised which showed that gold could be effectively loaded into DBC up to 190 g/L Au
