Mineralogical and geochemical analyses of the Dopolan karstic bauxite ore were performed to identify the characteristics of four bauxite horizons, which comprise from top to bottom, bauxitic kaolinite, diasporerich bauxite, clayrich bauxite, and pyriterich bauxite. Diaspore, kaolinite, and pyrite are the main minerals; böhmite, muscovite, rutile, and anatase are the accessory minerals.

Online elemental analysis is increasingly being adopted in the mining and processing of bauxite. At an Alumina plant a PGNA analyser is required on the bauxite feed to the stockpile yard to calculate the Alumina Module (Al:Si ratio) of bauxite. The bauxite deposit has four distinct qualities characterized by the Alumina Module.
The results of the present study also showed that among gastrointestinal cancers, the gastric cancer had the highest rate of mortality in Iran during the study years. Most of the gastric cancer sufferers in Iran are in the development stages of the disease and are noncurable 2426 and their surveillance is .
The growth effect of the increase in exports, related to the development of the mining sector (bauxite) and continued elevated aluminium prices, should be offset by the high price of oil, of which the country is an importer, and the upturn in imports related to investments.
1 天前· FeAl2O3 composites were prepared by pressureless sintering, using Bayan Obo iron concentrate and bauxite as the main raw materials, activated carbon was added as the reducing agent. The effects of different bauxite additions on the phase composition, microstructures, mechanical properties, and the corrosionresistance were investigated. The results show that the average grain .
