Description

f The invention relates to the flotation enrichment of minerals. No. 403425, a device is known for automatically controlling the flow rate of xanthogen entering the mill, the xanthate dispensers in the mill and in the flotation process, analog computing units, the xanthate concentrate meter in the pulp liquid phase, the solid flow meter in the pulp; the control unit and the regulator, while the outputs of the xanthate dispenser in the mill and the ore flowmeter are connected to the input of the first analog computing unit, the output of which, together with the output of the xanthogen concentrator meter, in the slurry liquid phase is connected to the input of the second analog computing unit, the output of which is together with the output of the flow meter hard at the pulp is connected to the input of the control unit, the output of which through the regulator is connected with the input of the xanthate dispenser in the flotation process l. The known device does not allow to optimize the consumption of xanthate in the process of flotation, taking into account the absorptive capacity of the pulp. The absorptive capacity of ore slurries with respect to reagents, in particular xanthate, varies widely. At the same time, in accordance with the mechanism of action of xanthogenate, its consumption increases with an increase in the absorptive capacity of the ore. The main amount of the collector is absorbed by slimes of enclosing rocks, therefore, a decrease in the absorber capacity of the ore pulp after grinding is possible as a result of the de-spamming process. However, a decrease in the absorptive capacity of the pulp is possible by treating it in the grinding process with an apolar reagent, such as kerosene. The aim of the invention is to increase the control accuracy by adjusting the pulp absorption capacity. This goal is achieved by the fact that the device for automatic xaragen xaragen storage is equipped with a regulator and a dispenser of apolar reagent into the mill, while the regulator of apolar reagent at input 355 is connected to the output of the second compiler. the output unit is connected with the apolar reagent dispenser, which is connected to the second input of the xanthate consumption regulator in the flotation process. The drawing shows a block diagram of the device. The device consists of the secondary device 1, the ore consumption recorded in the mill, the xanthate dispenser 2 in the mill, analog computing units 3 and 4, the xanthogen concentrator in the liquid phase of the pulp 5, the control unit 6, the flow meter 7 solid in the pulp, the regulator 8 and the xanthate dispenser 9 to the flotation process, the regulator 10 and the apolar reagent dispenser 11 to the mill. The device for automatic control of xanthate consumption operates as follows. The signals from the secondary ore consumption device 1 and the xanthogen dispenser 2 are fed into the mill to the input of the first analog computing unit 3, the output of which is equal to the ratio of the input signals, and is proportional to the specific xanthate consumption to the mill. This signal together with the signal of concentrator 5 xanthate in the liquid phase. the classifier drain, a proportional value, is fed to the input of the second analog computing unit 4, whose output signal is also equal to the input ratio, i.e. proportional to the ratio. (absorption module). Computing unit 4 has two outputs. The signal from the first output together with the signal ° of the flow meter 7 solid in the pulp is fed to the input of the control unit, in which, in accordance with the algorithm put in, they multiply and the resulting signal proportional to the specific consumption of the reagent is fed to the input of the regulator 8. In According to this signal, the controller changes the capacity of the metering unit until the feedback signal from the metering unit becomes equal to the input signal. At the same time, the signal from the second output of the computing unit 4 is fed to the input of the TO controller, which, in accordance with
