The purpose of processing was to transform raw lead ore extracted from the vein into pure lead. This involved many steps. The first was to wash, sort and dress the ore. Initially the process was very crude, often done by women and children. There was no crushing machinery, and no mechanical sieves. Just hands, hammers and water.
