Description
Известный способ получени хлористого бари путем обжига шихты, состо щей из баритсодержащего сырь , хлористого кальци и углеродсодержащего материала, например угл , с последуюндим выщелачиванием продукта обжига не обеспечивает непрерывности процесса и высокой степени использовани реагентов .A known method for producing barium chloride by burning a mixture consisting of barite-containing raw materials, calcium chloride and carbon-containing material, such as coal, followed by leaching of the calcination product does not ensure continuity of the process and a high degree of reagent utilization.
В предлагаемом способе с целью обеспечени непрерывности процесса и повышени степени использовани реагентов обжиг ведут при содержании в шихте углеродсодержашего материала в весовом отношении к баритсодержащему сырью 0,5-1 : 1. Процесс осуществл ют при 800-950°С параллельно в двух технологических потоках, причем в первый поток ввод т уголь или кокс, а в другой поток- пе растворившийс при вьицелачивании остаток.In the proposed method, in order to ensure the continuity of the process and increase the degree of use of the reagents, the calcination is carried out with the content of carbon-containing material in the mixture in a weight ratio to the barite-containing raw material 0.5-1: 1. The process is carried out at 800-950 ° C in parallel moreover, coal or coke is introduced into the first stream, and the residue dissolved in the extracellularization in the other stream.
Дл св зывани вредных примесей в шихту ввод т реагенты, например карбонат кальци , св зывающий двуокись кремни .Reagents, such as calcium carbonate, bonding silica are introduced into the mixture to bind harmful impurities.
Пример. Шихту, содержащую 1,6 кг баритового концентрата (84,7% BaSO4), 0,73 кг хлористого кальци , 1,3 кг коксовой мелочи (1 ; 0,46 : 0,81), нагревают при 950°С в течение 30 мин. Порошкообразный продукт обжига обрабатывают водой при 70°С. Количество извлеченного в раствор хлористого бари составл ет 1,12 кг.Example. The mixture containing 1.6 kg of barite concentrate (84.7% BaSO4), 0.73 kg of calcium chloride, 1.3 kg of coke breeze (1; 0.46: 0.81), is heated at 950 ° C for 30 min The powdered calcine is treated with water at 70 ° C. The amount of barium chloride extracted in the solution is 1.12 kg.
Нерастворившийс остаток в количестве 1,75 кг смешивают с 1,43 кг баритового концентрата и 0,72 кг хлористого кальци и полученную шихту прокаливают при 950°С. Образуюшуюс порошкообразную массу обрабатывают водой, извлека в раствор 1,07 кг хлористого бари .The undissolved residue in the amount of 1.75 kg is mixed with 1.43 kg of barite concentrate and 0.72 kg of calcium chloride and the resulting mixture is calcined at 950 ° C. The resulting powdered mass is treated with water, extracted into a solution of 1.07 kg of barium chloride.
Выход хлористого бари из обоих потоков составл ет 2,19 кг или 92,4%.The yield of barium chloride from both streams is 2.19 kg or 92.4%.
