Pure lead itself melts at a relatively low 327 degrees C, much lower than other minerals in the ore. The molten metal can be drained from the fire hearth into a collection container and can then be poured into moulds/ingots of pure lead metal. Initially, the smelted lead contained many impurities, reducing its value.
