Solubilization Processing of Ashes Power Plant

Abstract: The paper presents the attempts of acid and alkaline solubilization of the power plant ashes, using different chemical reagents, at different concentrations. Due to the mineralogical content of these ashes, was elaborated a technological flow for the recovery the iron minerals, resulting an ferrous concentrate containing noble metals. For their recovery from ferrous concentrate, were studied properties of gold, silver and platinum, the conclusion being that these chemical elements can be extracted, in economic… Show more

“…Briefly, the new methodology consists of the recalculation of a densimetric analysis on a coals blend, the washing curves tracing for any ash content (to determine the theoretical recovery vt) and the calculus by the Fournol method of the possible recovery, vr [3,4].…”
