Jan 01 2002 Phosphate ore used in this investigation was obtained from the phosphate deposits in the Mazda. The sample was crushed ground and then sieved to 250355 355500 500710 7101000 m size fractions using ASTM standard sieves.Chemical analysis of the phosphate ore was carried out by standard gravimetric volumetric and spectrometric methods and the results of chemical analysis.
The calcination and the reduction behaviors of a low-grade manganese ore by methane was studied at 973 K to 1273 K by several techniques. The onset temperatures of thermal decompositions of pyrolusite and calcite phases for this ore were found to be 868 K and 1056 K and the rates of decompositions are obtained as 1.4 10 -3 s -1 SUP and 1.53 10 SUP -3 SUP s SUP -1 SUP respectively.

Apr 15 2020 In the production of alumina Al2O3 from clays by acid leaching thermal activation by calcination is applied widely as a pre-treatment to improve the dissolution of aluminum. Previous studies have focused only on the thermal behavior of high-purity kaolinite and pyrophyllite individually. However thermal activation of complex clay ores containing several silicate minerals and their effect.
