Abstract:
A method of segregating a mineral stream into a first fraction substantially meeting a particular customer specification and a second fraction requiring further processing such that the proportion of the mineral stream in the first fraction is maximized, comprising:(a) observing a value of a selected parameter for a plurality of segments of the mineral stream to establish an original minimum history of data values; (b) creating an existing model to fit the minimum history; (c) obtaining a new value of the parameter for a particular segment of the mineral stream; (d) determining whether the new value is likely in view of the model; (e) calculating a cutoff value based on a current target value; (f) making a segregation decision based on whether the new value is above or below the cutoff value; and (g) repeating steps (c)-(f).
