This article suggests an approach of sustainable development in Cuba based on the environmental impact assessment of mercurial sludge generated by a chloralkali Cuban plant. It consists of a study of mercury mobility and availability in the sludge samples using sequential extraction procedure.
Mercury is extracted by heating cinnabar in a current of air and condensing the vapor. The equation for this extraction is HgS + O 2 → Hg + SO 2. In 2005, China was the top producer of mercury with almost twothirds global share followed by Kyrgyzstan.
