Thermal transformation of high chromium content flocculated tannery wastes with various additions of silica: application to the colouring of container glass

A colourant was synthesized using flocculated tannery wastes with a high chromium content, to which silica was added before calcination. The mineralogical evolution was described as a function of silica content and of given granulometry. An optimization of mineralogical composition and operating con...

Summary:A colourant was synthesized using flocculated tannery wastes with a high chromium content, to which silica was added before calcination. The mineralogical evolution was described as a function of silica content and of given granulometry. An optimization of mineralogical composition and operating conditions was performed in order to obtain an inert product (no hexavalent chromium) and to fulfil requirements of end-users (e.g. the glass industry) in terms of colour and fusibility.
