Benefication and Utilization of some local sand deposits for glass manufacture

Abstract

Some physico-chemical studies on local sands were carried out on 12 samples collected from Egyptian Glass Company. which were deliver from Zafrana region during the period from July 1999 to January 2000. In order to study the suitability of these sands to produce good quality of glass, some test experiments were done using these sands as major constituent for glass production. These studies include the following experiments:-

1- Mechanical analysis This method of analysis is used for the determination of the percentage of fine and coarse sands and the effect of chemical treatment on them .

2- Treating the different samples by washing with water and acid solution

{hydrochloric acid 10% }.

3- Chemical analysis This method of analysis includes the determination of the percentage of iron oxide ( Fe203 ) and silica ( Si02 ) content before and after treatment. also several other analytical methods were used

including:- I -X- ray fluorescence method In this method was used to determine the percent of Fe203 and Si02 present in sands, before and after sieving and in glass after melting. II - Atomic Absorption Analysis This method is used for the determination of percent of Iron oxide ( Fe203 ) . III - Colorimetric Analysis This method was also used to confirm the percent of Iron oxide ( Fe203 ).

4- Spectrophotometric Analysis these studies for some prepared glass samples were carried out to compare their transparency and suitability for commercial application.
