Jun 01, 2001· Abstract. As part of an EC programme oxalic acid leaching technology has been studied on the pilot scale to reduce the iron content of the silica sand for use in the production of clear flat glass. Heated sulphuric acid is usually employed for this purpose causing environmental problems with neutralisation and discharge of leachate effluents.
