The field of mineral processing has also been given other titles such as mineral dressing, ore dressing, mineral extraction, mineral beneficiation, and mineral most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or.
Dressing was the process of sorting out the raw materials (bouse) extracted from the mine the miners brought the bouse to the surface it was stored nearby in stone built storage hoppers caller bouse teams from where it was ultimately taken to a 'dressing floor', the area where the sorting took place often one dressing. Ore, around 70 per cent lead, was sent to the smelt mill, the rest being put through parts of the dressing process again for further treatment separate from the mine was the smelt mill, the position of which was determined by the local topography, roads from the mines it served for economic and effective transportation. The material brought out of the mine was called 'bouse', and was tipped into bays known as 'bouse steads' or ' bouse teems' for the first stage of processing women and children hand-crushed the bouse on a dressing-floor with small flat hammer-like tools called buckers at a later stage, water-powered mills with crushing.

Mills used in the mining industry and ore dressing plants are examples of major bottlenecks in the context of downtime concerning the production of metals ( expert) the mills have to be stopped due to planned or unplanned repair, and these stoppages lead to heavy monetary losses due to production losses inside the mill.
