Development of White Carbon, Silica Gel and Aluminum Sulfate from Clay Minerals

ABSTRACT

In this study the attempts were made to investigate the possibilities of using domestic clay minerals and zeolite, which are available in almost unlimitted quantities, for preparation of aluminum sulfate, white carbon and silica gel. Aluminum sulfate was obtained by the method of sulfuric acid treatment. White carbon and silica gel were prepared by utilizing crystalline silica which was obtained as a by product during preparing the aluminum sulfate. White carbon was obtained by reacting 5.0 weight percent sulfuric acid solution with water glass which was a reaction product of crystalline silica and soldium hydroxide in a autoclave, while silica gel was obtained by reaction 10.0 weight percent acetic acid solution with water glass.
