Chemical And Physical Investigations On The Barite Of Ain Mimoun Ore Deposit –khenchela - North-eastern Algeria

Authors : Abdellaoui Khedidja .

Abstract

In this work, we are interested in the barite of Ain Mimoun of the region of the wilaya of Khenchela-Algeria. This ore has not been chemically and physically studied before. This mineral is used in various industries for its special properties: high density, chemical neutrality, whiteness and no abrasive. Among which, it serves as a mineral filler in a wide variety of products including paints, paper, glass, rubber, plastics, friction materials and barriers for protection against radiation. The Ain Mimoun barite deposit remains one of the important sites for the production of barite primarily intended for oil fields as a weighting of the drilling mud. For this purpose, various techniques have been deployed, such as X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), differential thermal (DTA), Thermogravimetric (TG) analysis, and photoluminescence optical properties (PL). Various oxides and / or hydroxides associated with this mineral have been found, especially oxides rich in silice, iron, zinc, copper, etc. The estimation of the quantity of strontium in this barite was proposed in this work. The coexistence of numerous minerals testifies to the richness of this study area.
