In recent decades, emphasis was on improvement the Algerian mining industry by creating new smelting complexes such as the metallurgical plant in Bellara (Jijel) with a productive capacity of 5 million tons per year to satisfy the increasing demand in steel. The present study was conducted at Anini's iron ore mine to develop its mineral resources in order to use it in the metallurgical industry (Arcelor-Mittal complex of Annaba Algeria).Representative samples were collected from the iron ore mine of Anini in northwestern of Setif. A series of chemical and mineralogical analysis was performed. However, the analysis by (XRD, SEM and XF) shows that this mineral is hematite iron type clay and siliceous gangue. Moreover the mean levels of Fe2O3, SiO2 and Al2O3 are 50.52 %, 24.06% and 7.80%. The results obtained with the magnetic separation in wet process reveals significant content of iron ore with 65.1 1% of Fe2O3, 2.46% SiO2 and 1.73% Al2O3. These findings proved the effectiveness of this treatment to provide the criteria imposed by the steel industry. As well as the resulting wastes can be used in the cement industry.

Excessive concentrations of heavy metals introduced into the environment may represent a potential risk for all living organisms, including humans. Annaba has a strategic geographical location in terms of its natural potential, its various infrastructures, etc. The dense of industrial base characterized by the existence of large industrial complexes such as: Arcelor Mittal (steel), Fertial (fertilizer phosphatic), Ferrovial (metallurgy and boiler).Annaba is also one of the most polluted industrial and urban centres of Algeria. A long-term monitoring of air quality parameters in this area gives evidence of pollution by heavy metals. In this study, soil samples were collected from different sites of the city and analysed by atomic absorption spectrometry. The assessment of heavy metal pollution was derived using the total index of pollution. According to results study, the degree of technogenic pollution rated as “moderately threating” near the steel plant of El-Hadjar and in the centre of Annaba. Meanwhile, the relative reduction in the value of biomass in radish sprouts in the remaining three zones was 10-25%, whereas the protein content in the roots of radish plants were at the level of 0.6 - 0.8 times in comparison with the reference area of airport. © 2015 Vasile Goldis University Press.

Urbanization and increasing of industrialization have played a key role in the evolution of Annaba region. These activities were synonymous with economic and social progress. Annaba has known recently many problems in ecological terms, due to various urban pollutants (waste disposal, mining, smelting, and chemical industries etc.). In fact, large concentrations of chemical substances introduced into the environment may represent a potential risk for all living organisms, including humans. In our study, soil samples were collected from different sites of the Annaba city. The content of eight soil heavy metals (Pb, Cu, Zn, Cd, Fe, Mn, Ni and Co) was measured in the collected samples. According to analysis results, the highest degree of soil contamination with lead, copper, iron, manganese and zinc, was found in Annaba center and the area of sidi Amar located in the southeast, near the steel plant of El Hadjar. Meanwhile, the content of cadmium, cobalt and nickel in soils of all four studied sites, was at the level of geochemical background.
