Sepiolite -a by-product of exploitation as a potential raw material in Serbian industry

Abstract

This paper gives a brief overview of the sepiolite deposits, the basic properties, and the possibilities of using this mineral. Particular attention is paid to sepiolites from domestic production, especially the use of sepiolites suitable for the development of small businesses and technologies, with a focus on environmental protection. Aim of this paper is to point out importance of this mineral and to draw attention to the use of domestic raw materials. With appropriate mechanical and chemical pretreatments, sepiolite is shown to be useful in following applications: NCR paper, drilling fluids, absorbents, carriers for chemicals, animal nutrition, agriculture, decolorising agents, cosmetics and pharmaceutical uses, etc.

“…Two example ancillary minerals are considered for the capture of in-situ generated CO 2 (Equation (1)). fused milled perlite, a naturally occurring volcanic glass (potassium aluminum silicate), which, when heat expanded and milled, has an eggshell-like platy morphology (Omyasphere ® 200, Omya International AG, Oftringen, Switzerland), having 98 w / w % of particles ≤ 200 μm [ 8 , 9 ], Figure 1 b, and an intercalating mineral, sepiolite (magnesium silicate hexahydrate, palygorskite) Figure 1 c, a soft white clay having a needle-like fibrous particle morphology, displaying particles of 1–5 μm in length [ 10 ], historically known for the manufacture of clay smoking pipes [ 11 ]. …”
