The lihir gold project; Process plant design - ScienceDirect

01/08/1993  These preliminary batch tests are summarized in Table 2. They showed all Lihir ore types to be highly amenable to autoclave treatment. Gold extractions higher than 90% were achieved from all ore types, with extractions of 94 % to 96 % being common. The rate and ultimate extent of sulphur oxidation achieved in these batch tests was higher than Sherrill: had typically seen with other refractory sulphide gold
