Barium oxide (BaO) is formed by the oxidization of Barium salts such as barium carbonate, so the barium burns in oxygen to produce Barium oxide. Therefore, the chemical formula of Barium Oxide is BaO. The chemical reaction for the generation of Barium Oxide is as follows. 2Ba + O2 → 2BaO.

Process and Figure 1b shows the process flow diagram of the BaSO. 4CaCO. 3 . sludge separation process. The aim of this study was to separate calcium carbonate from barium sulphate, produced in the third stage of the CSIRABC Process, through dissolution of CaCO. 3. with CO. 2. By adding CO. 2. to a mixed BaSO. 4CaCO. 3. sludge, selective ...

bariumcarbonate) Process is a most costeffective process as the sludge produced is processed back to the process raw materials and valuable byproducts, such as sulphur. Coal is the main material used in processing the sludge.

Barium carbonate is made from barium sulfide soln by one of two methods. In the first, the soda ash method, the barium sulfide soln is treated with sodium carbonate, either dissolved or in solid form, producing barium carbonate and sodium disulfide. ... The usual operating temp is 6070 °C.

A nonthermal process for producing barium carbonate from barite by means of mechanochemical treatment has been developed. This process is composed of three steps: The first step is to produce barium hydroxide and potassium sulfate powders by milling of the barite and dry potassium hydroxide powder mixture in a mill.

Carbonation Method. The process of production of BaCO 3 with the carbonation process involves the following: First carbon dioxide is passed through a solution of barium sulfide so that it can carbonize, The barium carbonate slurry obtained from this process is .

carbonate. Volman (1984) overcame the cost problem by demonstrating that barium sulphate could be recovered and reduced efficiently and economically with coal under thermal conditions to produce barium sulphide. This compound can be used directly for the process or converted to barium carbonate. Wilsenach (1986) demonstrated the economic ...

 · The two most prevalent naturally occurring barium ores are barite (barium sulfate) and witherite (barium carbonate). In 2001, 542,000 tonnes of barium carbonate were produced globally. In Korea the estimated production volume of barium carbonate was 26 626, 10 681, and 16 452 tonnes/year in 2002, 2003, and 2004, respectively.

 · A method of producing barium carbonate comprising the steps of. a) heating coal tar pitch at a rate of 10° C./minute to a temperature between 350° C. and 450° C., maintaining the temperature for 816 hours to form mesophase pitch; b) adding barium sulfate to said mesophase pitch to form a reaction mixture, wherein the weight ratio of coal ...

 · Better results were obtained by substituting barium carbonate for K2CO3, as in the process of Margueritte and DeSourdeval (1861). Air (deoxygenated by hot carbon) was passed over a previously ignited mixture of BaCO3, ironfilings, coal tar, and sawdust, whereby barium cyanide is produced.

Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: BaCO 3 + 2 HCl → BaCl 2 + CO 2 + H 2 O. Pyrolysis of barium carbonate gives barium oxide. Uses. It is mainly used to remove sulfate impurities from feedstock of the chloralkali process.
