The resultant effluent from this process is neutralised with lime and the precipitate, calcium sulphate, is left to settle out in lagoons. The process is very effective in reducing the iron staining in sand but the procedure is energy intensive, uses hazardous chemicals and requires large areas for settlement lagoons.Bioleaching of Industrial Minerals - University of,,Fig. 2 – Silica sand entering the hot acid leaching process.

Iron removal by acid leaching separation is based on the fact that quartz is insoluble in acid (except H, impurity minerals containing Fe can be dissolved by acid solution), so that the purpose of removing iron-bearing minerals from quartz sand can be achieved. The acid leaching method can not only remove iron-bearing minerals from quartz sand,Silica Sand Etching Behavior During Leaching Process,The aim of this study is to show how the design of experiments method (DOE) could be used as a practical method to model silica sand etching behavior during the leaching process. In the present work we have studied the etching effect on the particle granulometric size during a primary step of the leaching process on Algerian silica sand with hydrofluoric acid (HF) at
