Production and purification of zircon opacifier from zircon found in the coastal area of Bangladesh S. Naher, A.S.M.A. Haseeb 1. Introduction Opaque glazes are those sufficiently low in light transparancy as to effectively hide the body fromthe view. They usually are white, but this is not a requirement. Zircon is classified in that type of inert opacifiers which remain in the glaze essentially in the same form in which they are added. The performance of an opacifierPROCESS ENGINEERING - zircon-association.org,Micronised zircon is used as an opacifier in the production of engobes, opaque glazes, and porcelain tile bodies [1–2]. The price of zircon, as for other materials, is largely driven by supply-demand factors. Elevated price levels, as seen in 2011–2012 (Fig. 1), tend to incentivise thrifting and substitution of zircon by alternative materials. In mostThe upgrading of an inferior grade zircon to superior,,zircon to superior opacifier for sanitary ware and glazes by E. Snyders*, J.H. Potgieter†, and J.T. Nel‡ Synopsis The upgrading process of an inferior grade of zircon to a superior opacifier for ceramic applications was investigated. A calcining process in the presence of mineralizers was used to produce the product in a conventional muffle furnace. A pre-milled inferiorMILLING AROUND ZIRCON OPACIFIER MARKETS AND TRENDS,220,000 tonnes of milled zircon was exported either as flour, opacifier or processed intermediate products such as frits and glazes. Those countries with a surplus of milled zircon are in Europe, principally Spain, Italy, Germany and the Netherlands, and in Asia, principally Japan, Korea and Taiwan. Australia and South Africa are alsoZircon - repository.up.ac.za,a. Zircon as opacifier . Opacifiers are an important market for zircon in the ceramic industry. Zircon imparts high opacity and extreme whiteness to the glaze. It also improves colour stability and assists in the development ofdesirable properties on the fired glaze surface. Typically, zircon glaze uses 8 (PDF) Production and purification of zircon opacifier,The main disadvantage of using ZrO2 as an opacifier is the high cost of its production by process of removing silica from zircon in electric furnaces. Therefore at present zircon, i.e. zirconium silicate (ZrSiO4) is being used for this purpose, primarily, for its lowcost and wide availability (Bhushan and Sen, 1965). Zircon sand occurs in the beach in the coastal area of Bangladesh along with,

In the first step, the raw material is subjected to magnetic separation. This process allows the separation of iron compounds. In the second step, the other contaminants are removed via solubility in hot sulphuric acid.
