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.

Opening Paragraph

Opening ParagraphThe Temne of the Northern Province of Sierra Leone are second only to the Mende in the Protectorate, numbering over half a million and inhabiting some 10,500 square miles of land. In general, they are culturally similar to their neighbours, especially in their possession of a number of societies, some secret, some not, which play integral roles in their lives. Of the societies found in this westernmost section of the Guinea Coast area, the Bundu or Sande for women and the Poro for men have been described by various writers for a number of groups. The emphasis placed on these two societies in the literature is justifiable in view of their multi-tribal geographic distribution, their general membership embracing most of the adult population and much of the adolescent segment in the groups where they are found, and the important functions they serve. In addition, however, there are a number of societies in this general area which, although they have a more restricted area distribution and less general membership, nevertheless also serve important functions for one or more groups. Such a society is the Ragbenle, also known as Maneke, which is centred in the eastern section of Temne country, where it is closely connected with the chiefs, particularly in conducting the ceremonies associated with their death, burial, selection, instruction, and installation, and, in addition, purifies violators of incest prohibitions, heals the chief and anyone else seeking help, divines witches, and provides other supernatural services. The purpose of this paper is to consider the membership of the society in terms of both supernatural and human members, and its functions in various aspects of Temne life.

Opening Paragraph

Opening ParagraphSeen in the widest perspective, 1787 is only one date among the uncounted tens, perhaps hundreds, of thousands of years during which the present Sierra Leone has been inhabited. Archaeologists have done disappointingly little work there. But it is clear from their findings (and by implication from findings in the rest of forest-belt West Africa) that people have lived there a very long time. Though traditional historiography always tends to present the peoples of Sierra Leone as immigrants from somewhere else, the language pattern suggests continuous occupation over a very long period. As Paul Hair (1967) has shown, there has been a striking linguistic continuity in coastal West Africa since the fifteenth century. Nor is there evidence to suggest that before that period stability and continuity were not the norm.

Waste Dumps

Knowledge of tailings characteristics is required for utilisation and management purposes in the mining and construction industry. Tailings from the mine waste dumps at Itakpe iron ore mine were collected and analysed in the laboratory to determine their chemical and physical characteristics and these include; permeability, porosity, specific gravity, particle size distribution, chemical composition and bioavailability factor of element. Geochemical speciation with quantitative X-ray powder diffraction was used to evaluate the chemical and mineral composition of Itakpe iron ore tailings. The aim is to offer base line data necessary to assess metal mobility and bioavailability. The distribution of heavy metals such as Cu, Ni, Cd, Cr, Zn and Fe was determined using multi- step sequential extraction. The results obtained indicate that the permeability is 6.24 x 10-3 cm/sec; porosity is 35%; and specific gravity is 3.58. The tailings is well graded and is sand gravel. Nickel and Zinc was found to be considerably high in exchangeable and bound to carbonates fraction which are mobile region and is bound to Fe – Mn oxides which is slightly mobile region but the higher concentration of Ni found in residual fraction. The implication of this result is that Nickel and Zinc partially enter into the food chain. Chromium and Cadmium concentration result indicated that these metals can easily enter into the food chain because of their presence in the mobile region and their higher mobility percentage.

Groundwater Drainage

The Forecasting of Groundwater Fluctuations is a useful tool for managing groundwater resources in the mining area. Water resources management requires identifying potential periods for groundwater drainage to prevent groundwater from entering the mine pit and imposing high costs. In this research, Auto-Regressive Integrated Moving Average (ARIMA) and Holt-Winters Exponential Smoothing (HWES) data-driven models were used for short-term modeling of the groundwater fluctuations in a piezometer around the Gohar Zamin Iron Ore Mine. For this purpose, 250 non-seasonal groundwater fluctuations data in the period 22-Nov-2018 to 29-Jul-2019, 200 data for modeling, and 50 data for prediction were used. To take advantage of all the features of the two developed models, the predictions are combined with different methods and specific weights. The results show better accuracy for the ARIMA method between the two short-term forecasts, while the HWES method requires less time for modeling. Also, among all the predictions made, the highest accuracy for the combined least-squares method is for forecasting the groundwater fluctuations in the short-term. All the forecasts show a decrease in the groundwater fluctuations, indicating pumping wells around the Gohar Zamin Iron Ore Mine area.
