Образующуюс суспензию раздел ют на барабанных вакуум-фильтрах.The resulting suspension is divided in drum vacuum filters.
Пасту карбоната бари промывают водой методом репульпации - фильтраци до OTcjTCTBHH 5 -иона в промывной воде и сушато Маточные растворы, содержащие .ц Си , возвращают в цикл на обработку раствора сернистого бари .The barium carbonate paste is washed with water by repulping - filtering until the OTcjTCTBHH 5 -ion in the wash water and dried. The mother liquors containing .ts Cu are recycled to the treatment of the sulfur barium solution.
П р и м е р. 162О г баритового кон центрата смешивают с 405 г кокса и гранулируют в присутствии сульфит-спиртовой барды. Полученные гранулы подвергаютPRI me R. 162O g of barite concentrate is mixed with 405 g of coke and granulated in the presence of sulfite-alcohol bards. The obtained granules are subjected
восстановительному обжигу во вращающейс бараба шой печи при 1100-1150°С. Образовавшийс плав сернистого бари в количестве 1000 г выщелачивают промывной водой, вз той в соотнощении 1:4 при к раздел ют.reduction firing in a rotary drum at 1100-1150 ° C. 1000 g of the resulting sulphuric barium melt is leached with wash water taken at a ratio of 1: 4 and the k is separated.
Полученные 4000 г осветленного раствра сернистого бари обрабатывают 2000 г 20%-ного раствора хлористого аммони и подают в карбонизатор, куда одновременно подают 285,1 г углекислого газа. Карбонизацию провод т при 40 С, осажда при этом карбонат бари . Образующуюс суспензию фильтруют на барабанном вакуум-филь тре, отдел ют пасту карбоната бари , промывают и сущат в барабанной вращающейс сущилке. Получают 720 г карбоната бари .The obtained 4000 g of the clarified solution of barium sulphide are treated with 2000 g of a 20% ammonium chloride solution and fed into the carbonizer, to which 285.1 g of carbon dioxide are simultaneously supplied. Carbonation is carried out at 40 ° C, while barium carbonate precipitates. The resulting slurry is filtered on a drum vacuum filter, the barium carbonate paste is separated, washed, and existed in a drum rotary nut. 720 g of barium carbonate are obtained.
Полученный продукт имеет состав по сравнению с продуктом по известному способу , приведенному в таблице.The resulting product has a composition compared to the product by a known method, shown in the table.
