In the mining industry, it is important to minimize the wastage of raw materials while achieving the desired particle size distribution by grinding the original input mix. To date, the procedure is performed manually, and there is no such control mechanism for grinding that reduces wastage to achieve the desired output, resulting in the loss of material.

Newer CNC mills rather use climb milling. The features of climb milling are: The cutting chip decreases in thickness, causing heating of the chip rather than the workpiece. The cutting surface is cleaner, resulting in less rubbing and an increase in tool lifespan. The chips fall behind the cutter, reducing the problem of a polluted cutting path.

The easiest way to improve efficiency in mining and to decrease waste products is to decrease a mine's mill cut-off grade. Re-evaluating these grades at each mine will significantly reduce waste. A lower mill cut off grade may decrease the quality of the material, but certain final uses of the material do not need a very pure compound.
