Catalyzing Carbothermic Reduction of Siderite Ore with High Content of Phosphorus by Adding Sodium Carbonate

Kinetic Study of Barite Carbothermic Reduction in Presence of Sodium Carbonate as Catalyst

KINETICS OF CARBOTHERMIC REDUCTION OF AN IRANIAN CELESTITE ORE

Two commercial methods are used for the production of strontium carbonate:1) Direct conversion of Celsetite to strontium carbonate by hot sodium carbonate,2) Carbothermic reduction of celestite with coal followed by water leaching of strontium sulfide(SrS) and its conversion to strontium carbonate.The present study has been made on the carbothermic reduction of celestite ores of Varamin (Iran) ...

Microwaves Applied to Carbothermic Reduction of Iron Ore Pellets

Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...

the effect of mechanical activation and sodium carbonate on the kinetics of molybdenite carbothermic reduction

in this research, kinetics of carbothermic reduction of molybdenite in the presence of different amounts of sodium carbonate has been studied. mixed powders consisting of molybdenite, graphite and sodium carbonate with three mole-ratios of 1:4:2,1:4:3 and 1:4:4 were mechanically activated for 40 hours. the results of x-ray diffraction on activated samples showed that no reaction occurrs in diff...

Carbothermic reduction synthesis of red phosphorus-filled 3D carbon material as a high-capacity anode for sodium ion batteries

Phosphorus is an attractive negative electrode material for sodium ion batteries due to its high theoretical specific capacity of 2596 mA h g . However, it suffers poor conductivity (10 12 S m ), slow reaction dynamics, and large volume expansion ( 440%) during the sodiation process, leading to rapid capacity decay upon cycling. Great attention has been devoted to improving the electrical condu...
