Preparation of porous materials using gold and silver mine's waste slime

摘要

Porous materials were prepared from mine's waste slime. The pore-formation process was observed with the samples treated in different temperature and time conditions. The liquid phase which comes from the decomposition of the sanidine and the muscovite-3T, explains the foaming reaction of mine's waste slime. Furthermore, in order to induce liquid formation and therefore to activate the foaming reaction, the alkaline oxide was added and its effects were examined.
