A method for determining the extent to which ores should be crushed and ground for optimum beneficiation in which dust is separated from the crushed ore and is then continuously sampled, and concentrated as to the desired mineral component and the concentrate continuously analyzed to determine the content of one of the mineral components thereof. The analysis is then used to determine the extent of grinding to control the composition of the final concentrate. Also the analysis may be used to proportion ore obtained from various sources to assist in controlling the composition of the final concentrate. |
