Dressing; Dressed; Dressing floor; Dressing plant

When metal ore compounds are mined they are usually brought out as a mixture of ore and other unwanted stone. This is called bouse, especially common for the Lead mineral Galena (PbS). To melt only the metal mineral compound it has to be dressed by separating from the bouse mixture. This can be done by hand or crushing the softer rocks in a crushing mill. The dressed Galena mineral is then washed in a washing floor. If this is done by hand it takes place on a dressing floor, a crushing mill can be called a dressing plant.
