Description

54) СПОСОБ УПРАВЛЕНИЯ ПРОЦЕССОМ ФЛОТАЦИИ54) METHOD OF MANAGING THE FLOTATION PROCESS

Изобретение относитс к области обогащени полезных ископаемых и может быть иснользовано при флотации полиметаллических руд на.обогатительных фабриках.The invention relates to the field of mineral processing and can be used in the flotation of polymetallic ores at enrichment plants.

Известен способ управлени процессом флотации путем изменени реагентного режима в зависимости от качественно-количественных параметров пульп1 1 l .There is a known method of controlling the flotation process by changing the reagent mode depending on the qualitative and quantitative parameters of pulp 1 l.

Недостатком такого способа вл етс невозможность коррекции управл ющих параметров процесса в зависимости от содержани полезного компонента в концентрате.The disadvantage of this method is the impossibility of correcting the process control parameters depending on the content of the useful component in the concentrate.

Известен также способ управлени процессом флотации путем изменени управл ющих параметров процесса в зависимости от содерлсс1ни полезно1« компонента в исходном питании 2 .There is also known a method for controlling the flotation process by changing the control parameters of the process depending on the content of the useful 1 "component in the initial feed 2.

Однако у этого способа недостаточна точность управлени процессом флотации, снижающа эф)ектиБность процесса.However, this method lacks the accuracy of control of the flotation process, which reduces the efficiency of the process.

Целью изобретени вл етс повышение точности управлени процессом флотации.The aim of the invention is to improve the accuracy of control of the flotation process.

Поставленна цель достигаетс тем, что прогнозируют- соотношение содержани полезного компонента в концентрате и хвостах, фор-The goal is achieved by predicting the ratio of the content of the useful component in the concentrate and tails,

мируют управл ющие воздействи пропорционально найденному соотношению с коррекцией по фактическому содержанию полезного компонента в концентрате.control actions are proportional to the ratio found with correction for the actual content of the useful component in the concentrate.

На чертеже изображена блок-схема, по сн юща предлагаемый способ управлени процессом флотации.The drawing shows a flowchart explaining the proposed method for controlling the flotation process.

Схема включает объект 1, на входе котс рого установлен датчик 2 содержани полезного компонента в исходном питании. Выход датчика св зан со входом вычислительного блока 3, выходной сигнал которого поступает на вход регул тора 4, На выходе объекта .установлен датчик 5 содержани ползеного компонента в концентрате, выходной ригнал которого измен ет управл ющие параметры объета .The circuit includes object 1, at the input of which a sensor 2 is installed, the content of the useful component in the initial power supply. The output of the sensor is connected to the input of the computing unit 3, the output of which is fed to the input of the controller 4. At the object output, a sensor 5 of the content of the crawled component in the concentrate is installed, the output signal of which changes the control parameters of the volume.

Claims

The method is carried out as follows. The content of useful KONmoHeHTa in the initial power supply O4, supplied to object 1, is determined using sensor 2, the signal from which, proportional to this content, enters the computing unit 3, where, depending on the magnitude of this signal, the ratio of the content of the field component in the concentrate is calculated and the tails and according to the given equations. The signal corresponding to the computational value of the unit 3 is fed to the controller 4 together with the signal from the sensor 5 about the Portioned content of the useful component in the concentrate. The input signals to controller 4 change the control parameters of the process N {air supply, retraction speed, reagent consumption and TjiJ according to the law N, n (jH,), fb h where N hp ,, n, t1, .. , P1 Mode of Mode Parameters. Analysis of the results shows that during the period of work on the proposed control method, a decrease in the zinc content in the tailings by 0, O67%, compared with the known is achieved. Positive results of industrial operation of systems including. The forecast for (b and V, obtained during the test period) testifies to the sufficient efficiency of the accepted principles. The application of the proposed method of controlling the flotation process at all factory processing levels significantly improves the technical and economical performance of the flotation. process parameters, depending on the content of the useful component in the initial feed, which is characterized by the fact that, in order to increase the accuracy of control of the flotation process, ognezuyut ratio of the content of the useful component in the concentrate and tails, form the control actions in proportion to the ratio found with the correction for the actual content of the useful component in the concentrate.
