Abstract In order to widen the industrial uses of Jebel Ad-Darin sand from Orbata formation of the region of Sened, different investigations have been made to determine the characteristics of the natural raw material using several techniques. The analyses were carried out by atomic adsorption, X-ray diffraction (XRD) as well as by microscopic observations under a scanning electronic microscope (SEM). Grain size analysis indicates the dominance of medium to coarse sands (> 250 μm) in our studied quarry, with good ranking and strong asymmetry towards small sizes. The mineralogical analysis by X-ray diffraction and scanning electronic microscope SEM showed that the sand of studied career consists essentially of quartz, whose percentage varied from 98– 100%.The chemical analyses of these samples confirmed these results. Mineralogical and physico-chemical characterizations indicated that the pure sand of Jebel Ad-Darin in Sened could be of great interest in the industrial sector. Keywords Grain-size analysis .

1 Introduction The world production of silica sand for industrial uses is around 140 Mt/year [1].Which is dominated by the USA (24%) and the Netherlands (20%) [1], while Tunisia’s share is insignificant. Silica (SiO2) is one of the substances present everywhere in the earth’s crust. It is also present in bedrock or in detrital sediments, and the sand is present in the form of mineralogical sets composed essentially of quartz and other families of minerals [2–7]. The source of sand is defined in nature as one of the products of erosion and alteration of the geological formations of a region [3, 5, 7]. According to Tunisian scientific studies, it is possible to draw appreciable benefits from sand in Tunisian regions, especially in Gafsa, which stands out for its superior quality. The proportion of silica in the sand varied between 87% and 99% by referring to various previous studies and recent research works [8–15]. A resource that can be used in

The present paper is interested in the locally available sands deposit in the region of Sened-Gafsa where, to the best of our knowledge, no studies have been carried out yet. The utmost objective of this study is to investigate the physicochemical and mineralogical features of sand from o
