Description
При получении синильной кислоты и ниднистого натри из,черного цианплава пр« очистке щелока, в цел х уменьшени расхода свинцовых солей или замены их другими соединени ми, предлагаетс применить оп ш;ление сернистых соединений воздухом и частичный перевод их в роданистые.In the preparation of hydrocyanic acid and sodium sulphide from black cyanplav in the treatment of liquor, in order to reduce the consumption of lead salts or to replace them with other compounds, it is proposed to apply air sulphide compounds and partially convert them to roanthanes.
Окисление ведут путем продувки воздуха (25-50-«ратное количество от объема раствора) в присутствии катализатора . Последним может служить любое свинцопзов соединение (100 г к более РЬО на 1 л щелоков): ЭтаOxidation is carried out by blowing air (25-50- “the amount of the volume of the solution) in the presence of a catalyst. The last can be any lead copy compound (100 g to more PbO per 1 liter of liquor): This
операци ведетс при энергичном размешивании до полного исчезновени сернтстых соединений.operation is carried out with vigorous stirring until complete disappearance of the sulfur compounds.
В дальнейшем раствор цианидных щелоков можно пускать на последующую переработку одним из известных способов.In the future, a solution of cyanide liquor can be started up for subsequent processing by one of the known methods.
Предмет изобретени .The subject matter of the invention.
Способ обессерквани цианидных щелоков лосредст1вом введени в них соединений свинца, отличающийс тем, что процесс обеосеривани ведут при продувании воздуха.The method of desulfurization of cyanide liquors by introducing lead compounds into them, characterized in that the process of co-sucking is carried out with air blowing.
