Acid-base properties of oxide systems in melts and aqueous solutions
Автор:Sarka Langova Год: 2011 Издание:LAP Lambert Academic Publishing Страниц: 96 ISBN: 9783844314748 Steel quality depends on various factors, i.a. on the slag basicity and oxidation potential. These values can be determined by means of emf measurement using solid electrolyte based sensors. Liquid iron can serve as a cation electrode. Activity of ferrous oxide and manganese oxide can be found out. Ferrous oxide activity determines the oxidation potential and manganese oxide activity can be used for the basicity estimation. Sulphide and phosphate capacity can be calculated and distribution coefficients of oxygen, sulphur, manganese, and other elements can be predicted. Metallurgical wastes are classified as hazardous because of high content of heavy metals and their waste disposal is problematic. Their hydrometallurgical recycling is difficult due to poorly soluble zinc ferrite. Thermal treatment is expensive because of high energy consumption. A new method of acid leaching applying diluted acids was developed. Entire zinc from the ferritic wastes can be extracted....
