India is gifted by nature by way of large quantities of high grade nonferrous mineral resources like barite containing more than 90% barium sulphate. The processing of barite to win chemicals from it requires its
carbotherrnic reduction at high temperatures being carried out in rotary furnaces. The powdered charge containing barium sulfide is prone to get damaged due to reverse reaction caused by infiltered oxygen at the end of
reduction state. This hampers the yield of water soluble barium sulfide.The paper discusses about the means of achieving favourbale kinetics and high recovery of water soluble barium sulphide in the carbothermic reduction of barite at high temperatures. The reaction rate of reduction
step was enhanced many folds by using briquetting technique. Even with barite containing large amnount of harmful impurites, the yield of barium was improved considerably on pilot plant scale, thus achieving better
utilisation of natural resoures such as barite and coke
