Abstract
Opening ParagraphLunsar is a town of some 10,000 people which has grown up since 1930 beside an open-cast iron-ore mine worked by the Sierra Leone Development Corporation (Delco) in the Marampa Chiefdom of the Northern Province, about sixty miles from Freetown. In the early days large numbers of unskilled workers were employed, but now the mine is highly mechanized. The ore is excavated and removed by mechanical scrapers and transported on a conveyor belt to a mill where most of the waste material is separated. It is then taken by conveyor belt to stockpiles and from there is mechanically loaded on to wagons.
