Production of High

Abstract. To produce high-purity silica sand usable for glass making, the present study was carried out. The objective of this work was to increase the silicon dioxide (SiO 2) content to at least 99% using a simple process without chemical input.The raw sand samples were taken from the Ivorian sedimentary basin, from Mafr and Assinie areas, C te d'Ivoire.

Silica Sand

04.09.2012To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170C (340F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.

Removal of iron from silica sand by leaching with oxalic acid

01.08.1997The maximum iron removal that can be achieved is approximately 25%, at leaching temperatures as low as 5 and 4-5 h retention time. 3.5.3. Effect of pH The effect of pH was studied through a series of tests conducted at 10, pulp density 60% (w/v), in a 0.2 M oxalate solution containing 5 mg/L Fe2+ with pH values varying between 1 and 5.

Comparative Study of Water

12.09.2018The acid treatments increased the crystallization temperature of silica to 1200 C and retained the amorphous state of silica for 2.5 h. In the case of water-leaching pretreatment, leaching duration for 2.5 h could yield an amorphous silica with purity of 94% and render the silica amorphous at 900 C for 7 h.
