Abstract ALLEGHENY LUDLUM E-BRITE 26-1 ALLOY is a low-carbon, low-nitrogen ferritic stainless steel made by a vacuum refining process. It provides: (1) Excellent resistance to pitting and crevice corrosion in chloride-containing environments, (2) Excellent resistance to chloride stress-corrosion cracking, (3) Resistance to intergranular corrosion, (4) Resistance to a wide variety of corrosive environments, and (5) Improved toughness and ductility after welding. Its applications include equipment for handling caustic, organic acids, nitric acid, bleach solutions, urea and chloride containing cooling waters. This datasheet provides information on composition, physical properties, microstructure, hardness, and tensile properties as well as fracture toughness. It also includes information on low temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-360. Producer or source: Allegheny Ludlum Corporation.

The main factor affecting the raw sugar refining process is certainly “colour”. The higher colour removal, the higher is the obtained sugar yield. Therefore, colour removal is the main goal throughout the process. In a conventional sugar refinery colour is removed in the purification and decolorisation steps – the second one is normally done using ion-exchange resins – but there are some other ways of colour removal such as adding some colour removing agents (powdered carbon, sodium bisulphite, PCC [precipitated calcium carbonate]). In this article the pilot plant results of experiments of increasing colour removal in the refining process are described, such as PCC addition, 3rd carbonatation (re-purification), hydrogen peroxide addition, powdered carbon addition, sodium bisulphite addition and crystallization improvements. The good results achieved in some of these trials led to perform some industrial trials, the results of wich are summarized in this article as well.

Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated a route to separate Sn, Sb, Bi, and Cu from tin anode slime after leaching with hydrochloric acid. In the solvent extraction process with tributyl phosphate, Sb and Sn were extracted into the organic phase. Bi and Cu were unextracted and remained in the liquid phase. In the stripping experiment, Sb and Sn were stripped and separated with HCl and HNO3. Bi and Cu in the aqueous phase were also separated with chemical precipitation procedure by controlling pH value. The purities of Sn, Sb, Cu solution and the Bi-containing solid were 96.25%, 83.65%, 97.51%, and 92.1%. The recovery rates of Sn, Sb, Cu, and Bi were 76.2%, 67.1%, and 96.2% and 92.4%.
