Možnosti získávání hliníku chemickým loužením z doprovodných surovin při těžbě hnědého uhlí

Abstract

Target of this thesis has been verify possibility obtaining aluminum by chemical leaching from accompanying raw materials from coal mining. For laboratory experiments were to be choice samples feint bitumen carbonattic claystone, puff – stone and swelling clay of Sokolov and Most basin. Thesis describes lead time activity before leaching, preliminary treatment ore, self leaching and follow-up obtaining ore of the leach. In laboratory part be described to chemical and mineralogical constitution choice samples, their granulity constitution and results chemical leaching. From results leaching follow on, that the to obtaining aluminum is using hydrated oxide unsuitable, becouse him obtained only small quantity aluminum. While using acids is this method acceptable, becouse reached as many as 50 %. This method is possible use too for materials low in required metals, because adjustment of conditions is possible achieve relatively good results.
