Description
Известные способы обработки пир.ктовых огарков, пр-едназначевных дл ут желени глинистых растворов, оанованы на усиленной промывке огарков, с целью удалени посторонних пр,имесей, ухудшающих качество глинистого раствора.The known methods of treating pyrtic stubs, which are suitable for smoothing out clay solutions, are designed for enhanced washing of stubs, in order to remove extraneous pr, mixtures that impair the quality of the mud.
Пре,длагаемый способ обработки пиритовых огарков заключаетс в том, что, с целью П|ре|дотвращени коагул ции глинистого раствора, после помола огарки подвергают двухкратной Х1им1ической обработке.The proposed method of processing pyrite cinders is that, in order to prevent coagulation of the clay solution, it is subjected to two-fold chemical treatment after grinding the cinder.
Первоначально ведут обработку огарков каль|цинирован|ной садой. При этой обработке в огарках нейтрализуютс сульфаты, которые превращаюто в вадиссоцишрованные карбонаты. Количество соды из|мен; ют в зависимости от садержаки сульфатов. Максимальный расход соды- 1,3% от веса опарков. Обработке /подвергаетс водна суспанзи огарков. После этого огарки обрабатывают каустической содой. При этом в огарках нейтрашизуютс сульфи|ды, которые превращаютс в не1диссодиироваиные гидроокиси. Количество едкого натра в зависимости отсодержа1НИ Я сульфндов дост1ипает 3% от веса огарков. Обработка Произво1дитс в суспензии огарков после нейтрализаци .кальцинированной содой на холоду или при иагреве до Т1емпбр1атуры кипе} и, .Initially, they cultivate stubs with a calcined garden. During this treatment, cinders neutralize sulfates, which are converted to vadissociated carbonates. The amount of soda from | depending on the sulfate sulfate. The maximum consumption of soda is 1.3% of the weight of the stock. The treatment is subjected to water suspension. After this cinder is treated with caustic soda. At the same time, sulfides are neutralized in the cinders, which are converted into non-dissigated hydroxides. The amount of caustic soda, depending on the amount of sulfide, reaches 3% of the weight of the butt. Processing Occurs in a cinder suspension after neutralizing with calcined soda in the cold or when heated to Titemper bale} and,.
В первом случае добавление нейтрализующих веществ производитс одновременно при общем времени нейтрализации 10 час.In the first case, the addition of neutralizing agents is carried out simultaneously with a total neutralization time of 10 hours.
Обработка при К1ип чении уменыиает врем нейтрализации. В этом случае в кип щую суспензию огарков добавл ют сначала кальцинированную соду и через 10 .мин. натр. В после(ДН1ем огарки выдерживают еще 30 мин.The treatment during cleaning increases the neutralization time. In this case, firstly soda ash is added to the boiling suspension of cinders and after 10 min. natr. In after (DN1em cinder is kept for another 30 minutes.
После Х1имичеокой обработки производ т отмьшку продуктов нейтрализации сульфата и сульфида натри холодщой водой- В результате получаетс высококачественный ут желитель глинистых растворов, поAfter chemical treatment, sulfate and sodium sulfide neutralization products with cold water are removed from the substrate. As a result, a high-quality product of clay solutions is obtained,
