2. The synthesis of alum proceeds in several reaction steps. The mole ratios of reactants and products can be found by combining the written equations for these separate reactions into an overall equation. Balance the overall equation for the synthesis of alum, KAl(SO4)2 · 12 H2O, from aluminum, potassium hydroxide, sulfuric acid and water.

Pretreatment of scrap by shredding, sieving, magnetic separa-Aluminum Manufacturing tion, drying, and so on is designed to remove undesirable substances that affect both alumi-num quality and air emissions. The prevailing process for secondary aluminum production is
B. ALUMINUM SULFATE. Aluminum sulfate, also called alum, became an industrial product in the 19th century. It was made by treating either bauxite or china clay with sulfuric acid. Unlike true alum, aluminum sulfate could not be conveniently purified through recrystallization because of its greater solubility in water.

Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.

Solid wastes from the production of secondary aluminum include particulates, pot lining refractory material, and salt slag. Particulate emissions, possibly containing heavy metals, are also associated with secondary aluminum production.

POTTERY PRODUCTION PRACTICES: Pottery Myths Since pottery is an endeavor that involves many steps—any of which can cause total failure—potters often misguidedly cling to a set method or technique that they think will provide a guaranteed result.
production amounted to only a few tons per year, bentonite production now exceeds a million tons per year (Table 1). In fact, average annual production over the past 10 years has exceeded 1~ million tons; 1956 was the highest production year with more than 189 million tons (U.S. Bureau of Mines
