The optimum parameters were 700g/t NaCN 46 solid in pulp pH=10 and d 80 =45 microns using the Taguchi method. So the gold recovery was obtained 90.71 . Also it was concluded that the NaCN concentration was the most effective parameter and the solid percent plus retention time had the lowest effect on this process.

From the literature it is apparent that in circuit design some approaches to the sizing of AG/SAG mills as well as the ball mills that they feed use this parameter. This paper reviews whether the

SAG Mill Process ControlGrinding Classification

If the SAG mill is not intended to be the rate-limiting step in a process plant then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example the hoisting capacity of the mine shaft is the rate-limiting step in the process and the SAG mill must adapt to
