Each possible mineral recovery process has a certain size range of best performance, and the final product of the crushing/grinding circuit must match the chosen process size requirements. Proper grinding is critical in order to get good metallurgical test results, as the entirety of downstream processing is dependent on optimal grinding and recovery at this stage.
