A comparative study on modeling and experimental data from this study proves that Box–Behnken design and RSM, in conjunction, could efficiently be applied for the modeling of ball mills in copper sulphide ore grinding. Promising results also suggest that RSM can be tested and developed for grinding modeling of other ores.
scroll for next step Using large grinding mills, ore is further crushed and ground to the consistency of beach sand. Because nature creates copper in low densities (typically less than 1 percent grade), copper levels must be increased or "concentrated" to be recovered economically. This is accomplished by the next step, called flotation.
