Изобретение относитс к гидрометаллургическим процессам разделени металлов, в частности, к способу управленн процессом селективного осаждени гидроокиси металлов и может быть использовано в химнческой промышленности и металлургии.The invention relates to hydrometallurgical processes for the separation of metals, in particular, to a method for managing the process of selective precipitation of metal hydroxide and can be used in the chemical industry and metallurgy.
Известен способ управлени процессом селективного осаждени гидроокиси металлов путем подачи нейтрализатора кислоты гидролиза до и после ввода окислител н стабилизации рН среды в процессе окислени и гидролиза металла l .There is a known method for controlling the process of selective precipitation of metal hydroxide by supplying an acid hydrolysis neutralizer before and after entering the oxidizer and stabilizing the pH of the medium in the process of oxidation and hydrolysis of the metal l.
Известен также способ управлени процессом селективного осаждени гидроокиси металлов, включающий регулирование соот- ношени расхода металла в растворе, псщаваемого на осаждение, расхода нейтралигзатора кислоты гидролиза металла,, осаждаемого в гидроокись, а также регулирование рН среды до н после ввода окислител 2J There is also known a method for controlling the process of selective precipitation of metal hydroxide, including regulating the ratio of metal consumption in solution to the precipitation, consumption of acid neutralizer acid hydrolysis of metal precipitated into hydroxide, as well as regulating the pH of the medium before n after the introduction of the oxidant 2J
Однако известные спсх;о6ы могут примеВ тьс лк1ль в процессах, где сэдержание ионов осаждаемого металла в растворе очен мало (до 1 г/л), а обрабатьшаемые потоки вепикв (более 2ОО MV4ac).,. However, known CPSS; o6s can be used lk1l in processes where the content of ions of the deposited metal in the solution is very small (up to 1 g / l), and the fluxes of vepikv (more than 2OO MV4ac) are processed.
В технологических процессах, где соде жание ионов осаждаемого металла препыпюет 1 г/л, а обрабатываемые потоки невелики (до ) применение- известных способов приводит к нов()1шенкю рИ в зоне окислени осаждаемого металла и поэтому снижает селективность осаждени металлов, увеличивает расходы нейтрализатора н окислител .In technological processes, where the content of ions of the deposited metal preppeps 1 g / l, and the treated streams are small (before) the application of known methods leads to a new () 1 scale in the oxidation zone of the deposited metal and therefore reduces the selectivity of metal deposition oxidizing agent
С целью устранени перечисленных недостатков в предлагаемом способе рИ срепы перед вводом окислител регулируют изменением расхода пульпы, отбираемой после окислени осаждаемого в гидроокись металла н оборачиваемый в рецикл, а рИ среды после окислени металла, осаждаемого в гидроокись , регулируют изменением расхода окислител , вводимого в оборачиваемую в рецикл пул1 пу nociie смешени ее с нейтрализатором кислоты гидролиза осаждаемого металла.In order to eliminate the aforementioned disadvantages in the proposed method, the PI of the oxidizer before regulating the oxidant is controlled by changing the flow rate of the pulp taken after oxidizing the metal deposited in the hydroxide and recycled into the recycled metal. recycle pul1 nociie mixing it with a neutralizer of acid hydrolysis of the deposited metal.
На чертеже изображена схема процесса, по сн юща предложенный способ.The drawing shows a process diagram explaining the proposed method.
Расход оборачиваемой в рецикл пульпн измер етс датчиком расхода 1, сигнал которого вл етс переменной регул тора 2The flow rate of recyclable pulp is measured by flow sensor 1, the signal of which is variable of controller 2
