A copper flotation flowsheet. because the copper in this type of ore usually assays only plus or minus 1 copper, the porphyry copper operations must be relatively large in order to be commercial. the flowsheet in this study illustrates a typical 3,000 ton per day operation. in general most operations of this type have two or more parallel.
Whether gold remains in porphyry copper deposits is important both to their economic attractiveness and to the distribution of gold in the upper crust. cuau atomic ratios of porphyry copper ore deposits form a continuous range from about 5000 to 5,000,000 with a median near 40,000, which separates goldrich and goldpoor deposits.
