Summary:The diversity of refractory ore types from disseminated Au ores along the Carlin trend, Nevada, has required the development of a sophisticated computer system which merges analytical and mineralogical data into a diagnostic metallurgical database. Metallurgical data obtained on bench scale are correlated with analytical and mineralogical data to provide a variety of process options for the treatment of refractory carbonaceous sulphide ores. Metallurgical samples are classified intoore types on the basis of mineralogical composition and analytical characteristics, and prepared into composites for test work. Ore types for the Carlin deposits include: siliceous, argillaceous, carbonate, diopsidic, pyritic and carbonaceous. Au extractions are compared with sulphide S and organic C assays and related to the degrees of oxidation of sulphides and C, in response to various metallurgical pre-treatment options before C in leach and conventional cyanidation.
