Grinding circuit data had to be reconciled due to inability to calculate the circulating load of these circuits with good accuracy. Complex circuit analysis with data redundancy in mineral processing historically requires a wide sampling campaign and the use of matrix calculation for each mineral component present in each considered flow.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
