Gibbsitic bauxite from Australia was leached by hydrochloric acid in this work. Analysis on kinetics for the extraction of Al 2 O 3 quantitatively studied. It concluded that leaching process gibbsitic controlled chemical reaction. Moreover, mechanism dissolution followed equation,<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mrow><mml:mi...
Abstract This work reported a process for the preparation of Portland cement clinker from sulfuric acid leaching residue coal fly ash. Aluminum and iron in ash were effectively leached by leaching, silica was all concentrated residue. The chemical analysis showed that content SiO 2 79.1% contained small amount Al O 3 , CaO Fe which could replace clay as raw material clinker. effects main conditions on quality prepared studied. results burnability with rate value KH = 0.92, SM 2.1, IM 1.2...
The oxide-scale structure and pickling behavior of oxided 2205 duplex stainless steel in the electrolytes containing hydrochloric acid were investigated. oxide scales mainly consist two layers: outer layer is dense Fe 2 O 3 , inner granular FeCr 4 spinel. During process, pittings form around boundaries particles or interfaces kinds oxides, which results that electrolyte can directly react with chromium-depleted along to produce an “undercut” effect so efficiency improved markedly. mechanism...
The traditional process of alumina production by acid method was to neutralize the aluminum chloride solution obtained leaching for preparing hydroxide, and then calcined produce alumina. This not only had many processes, but also high energy consumption. In this paper, properties prepared pyrolysis were studied chemical composition analysis, XRD SEM. Thermodynamics analyzed. effects temperature time on investigated. results showed that it would be completely feasible according thermodynamic...

The RH vacuum refining technology is a vitally powerful method of producing clean steel. inner diameter traditional circular snorkel very difficult to be increased owing the metallurgical refractory thickness around snorkels and limitation area under chamber, limiting increase in efficiency. In order improve efficiency reactor, new designed degasser with an optimized arched established. This design replaces two structure greatly enhances cross-sectional snorkel. this study, flow...
The present paper provides equations for the design of liquid collection layers sloping radially toward a sump located in corner layer. It is pointed out that an equation currently used by some engineers not correct because it corresponds to case confined flow, which type flow should take place layer; this leads grossly underestimated values required thickness and hydraulic transmissivity layers. A detailed discussion difference between unconfined presented. Design examples are provided.
