Technology of joint processing of nepheline and bauxite

Article preview

Due to the deficit of alumina at present, the main task of operating alumina refineries is to increase productivity. The proposed technology has been developed at Achinsk Alumina Refinery, but in the future it can be applied at other enterprises. The essence of the technology is combined processing of nepheline and bauxite ores. In this article the results of laboratory research carried out at present are considered. A preliminary summary of the feasibility of the proposed technology is given.

Improvement of nepheline speck leaching technology based on the use of combined coagulants-flocculants of the carboaluminate-alklar type

Article preview

The problem under consideration includes the solution of secondary losses of alumina and alkali during aluminate sinter leaching and improvement of technical and economic performance of nepheline slurry thickening and washing processes through the use of combined coagulant-flocculant additives of carbon-aluminate-alklars type. In accordance with the set tasks an analytical review was carried out, patent research was carried out and directions of further research were substantiated.
