Aluminum sulfate in aqueous solution was used as the raw material. High concentration of the precipitant agent promotes the formation of ammonium alunite, which was confirmed by XRD, TG/DTG and FTIR analysis. The ammonium alunite has less sulfate ions and more water than the BAS, and so, the ammonium alunite heat treated up to

Aluminium sulfate is a chemical compound with the formula Al 2 (SO 4) is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and waste water treatment plants, and also in paper manufacturing.

The paper reports a process for synthesis of γalumina from kaolin. Kaolin was transformed to metakaolin by calcination at 800˚C for 2h. alumina powder was synthesized thγ rough extracting alumina from meta kaolin via H2SO4 and metakaolin reactions and consequently precipitation in ethanol, which led to form the aluminum sulfate.

Potassium alum historically was mainly extracted from alunite. Potassium alum is now produced industrially by adding potassium sulfate to a concentrated solution of aluminium sulfate. The aluminium sulfate is usually obtained by treating minerals like alum schist, bauxite and cryolite with sulfuric acid.

Another method of production involves converting aluminum sulfate to potassium aluminum sulfate by adding potassium sulfate. In addition to these chemical processes, potassium aluminum sulfate is also found occurring naturally in minerals such as alunite and kalinite. Commercially available potassium aluminum sulfate is called potassium alum ...

Enriched alunite ore, containing 50 60% of alunite, is roasted at temperatures between 520о – 620о С for 1 – 3 hours. Roasted alunite is further leached with sodium carbonate solution (5–20 %). Proportion of sodium carbonate for binding of SO3 aluminum sulfate in alunite accounts for 100 – 110 % of stoichiometric quantities.

Feb 15, 1977· The application of the process is the production of monobasic potassium phosphate by ion exchange from wet phosphoric acid produced by the reaction of sulfuric acid on apatite rock and byproduct potassium sulfate from processes for the recovery of aluminum from alunite.
