Particle Size Analysis for Mining and Minerals

Particle Size Analysis for Mining and Minerals

In many cases the valuable minerals are mixed with gangue commercially useless material and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step concentration of the ore.

Principle #6Visualize and limit WIP reduce batch sizes

Reduce Batch Size. Another way to reduce WIP and improve flow is to decrease the batch sizes of the work—the requirements designs code tests and other work items that move through the system. Small batches go through the system more quickly and with less variability which fosters faster learning. The reason for the faster speed is obvious.
