· Abstract. In present study, the effect of extrusion process on kinetic of carbothermal reduction of barite was investigated. In order to improve the gasification rate potassium carbonate was doped on coke as catalyst. The mixture of barite and coke powder was shaped by a laboratory extruder and the reduction process was isothermally carried

Barite 4.20. Barite is the primary, naturally occurring, barium-based mineral. Barium, atomic number 56, derives its name from Greek and means heavy. Barite is also known as baryte. The primary countries in which commercial deposits of barite are currently found are the United States, China, India and Morocco. Barite’s high density and
