Aug 06, 2011· Aluminium sulfate having chemical formula of Al2(SO4)3.14H2O is known as alum. There are two types of alum - (i) Ferric alum and (ii) Non-Ferric alum. With bauxite, Non-Ferric alum can not be produced directly because of higher level of purity requirement. Broad specifications of Ferric alum conforming to IS 299 : 1989 are outlined below-

The plant uses raw materials of bauxite from Riau Islands (containing Al 2O 357.5%), with the modification of Bayer and Giulini Process. Aluminum sulphate production process is divided into three stages. The first stage is a digestion process that operates at a . temperature of 160˚C . and a pressure of 1 atm with the addition of NaOH 55% ...
to the problem is to recycle the used fabricated aluminum into other useful products or into aluminum compounds. This research illustrate a chemical process in which waste aluminum is converted chemically into an aluminum compound i.e. hydrated potassium aluminum sulfate, KAl(SO 4) 2 •12H 2 O, or commonly known as Alum.
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.

dry aluminum sulfate from Sweden, a dry white granular material used in water purification, waste water treatment, and for industrial uses. Petitioner has specifically excluded liquid aluminum sulfate from the scope of the investigation. The dry aluminum sulfate covered by this investigation has a minimum of 17
Aluminium sulfate is used in water purification and as a mordant in dyeing and textiles. In water purification, it causes suspended impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily. This process is called coagulation or flocculation.

The principal products covered in this report are alumina trihydrate (ATH), aluminum oxide, aluminum chloride, aluminum sulfate, alumina silicate, and sodium aluminate. Alumina trihydrate is typically produced from bauxite via the Bayer process; the vast majority of production is calcined and used for aluminum metal production.
Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.
In particular, leaching of pure oxides of Fe, La, Nd, Dy, and Y and bauxite residue (a solid residue generated by the Bayer process in the primary aluminum industry) was investigated using pure ionic liquid 1-ethyl-3-methylimidazolium hydrogen sulfate (EmimHSO 4). Rare earth oxides were found to totally dissolve in the ionic liquid at elevated ...
The most important and the most valuable process developed by Dabster is the production of aluminum sulfate from various raw materials. Dabster owns the technology and know-how to produce aluminum sulphate from such raw materials like kaolin, bauxite and aluminum hydroxide. The process occurs under conditions of elevated temperature and pressure and takes place in several .
Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.
Aluminium Sulphate Production Line. Aluminium sulphate is a metallic salt formed for commercial purposes by the action of 98% sulphuric acid on an aluminium source such as bauxite, kaolin, or aluminium oxide or hydroxide. The alum is produced at an Al2O3 content of 14-18% in the form of slabs, lumps or powder.
Process Aluminum Sulfate Aluminum sulfate is produce by the reaction of sulfuric acid on bauxite, a naturally occurring hydrated alumina. ore having the approximate formula Al2O3.2H2O. the mined material varies in composition and generally contains one to the three molecules of water plus impurities such as iron, silica, titanium, and .
48 Bauxite ore is the main source of aluminum for the world and contains various aluminum minerals and 49 two iron minerals (Amethyst Galleries 2014). The process creates hydrated aluminum sulfate per the 50 . following reactions: 51 . 52 . From bauxite: 3 H. 2. SO. 4 + 2 Al(OH) 3

The manufacturing process for all the forms of aluminum sulfate included in the petition involves reacting liquid sulfuric acid with either bauxite ore containing aluminum hydroxide (Al(OH)3) and hydrated aluminum (Al2O3∙3H2O), or synthetic hydrated aluminum previously refined from bauxite.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being .
