Removing Al and regenerating caustic soda from the spent

Spent liquor from washing of aluminum section materials after etching with caustic soda NaOH has been treated. Aluminum was removed from the liquor and caustic soda was regenerated by adding precipitating agents to hydrolyze sodium aluminate Na2AlO2, separating the aluminumprecipitate, and concentrating free NaOH in the resulting solution for reuse in the etching process.

Our processes feature improved mud separation and high wash effi ciency in order to maximize caustic recovery and ensure the highest quality end product. HOT digestion plant, Yarwun 1 alumina refi nery, Queensland, Australia Proven proprietary grinding solutions

Bayer process

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 3060 aluminium oxide Al 2 O 3, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to

Alumina: Filtration in the alumina production process

Jun 18, 2010· A typical alumina plant may use approximately 5001000m2 of filtration area per million tonnes of production as well as many hundreds of square metres of gravity thickener/clarifier area. Production of alumina has approximately doubled in the last 20 years to more than 80 million tonnes.

Bauxite

bauxite in the Bayer process is called the Total Available Alumina TAA. It is made up of two parts: THA Trihydrate Alumina. This is the alumina that is extracted in a low temperature refinery. MHA Monohydrate Alumina. This is the extra alumina that will be extracted in a high temperature plant.

PET Bottle Washing/Recycling Plant In this section, well focus on the process of cleaning PET bottles and processing them into recycled PET plastic, or RPET for short. When the plastic bottles arrive at a PET recycling / washing plant, they are usually in large bales that have already been separated by color.

Alumina Refining  The Australian Aluminium Council

This dissolves the alumina content of the bauxite. The solution is then cooled in a series of flash tanks. Clarification. The impurities which remain undissolved are allowed to settle as a fine mud in thickening tanks. After several washing stages to recover caustic soda, the residue is pumped to storage dams. The solution of alumina

Recycling of aluminum and caustic soda solution from waste

Mar 15, 2011· The purity of the aluminum salt was improved after washing the precipitate with deionised water. The characterization of the solid recovered, performed by thermogravimetric analysis, Fourier transform infrared spectroscopy and X ray diffraction, indicated characteristics typical of bayerite.

Recycling of aluminum and caustic soda solution from waste

Mar 15, 2011· Second and third washing steps also allowed a significant removal of contaminants. The fourth washing step had a marginal effect on the removal of contaminants elimination of 1.5 and 0.8 of sodium and sulphates, respectively. Fig. 4 also shows the impact of successive washing steps on the leaching of aluminum from the solid recovered. The
