In the article considered the control of reagent conditions of flotation copper-nickel ores, it is proposed to take into account in the control algorithm residual ion concentration of sodium dimethyldithiocarbamate (DMDK) in the pulp. Flow control DMDK based on the residual con- centration of its ions in flotation pulp provides optimized reagent conditions and improves the qualitative rate of enrichment copper-nickel ores with the simultaneous reduction of material costs for the implementation of the operation.
This article introduces the functional diagram and calculation methodology of the automated control system the flotation of copper-nickel ores, based on the optimization of reagent conditions and parameters of froth. Their use in the design stage control system guarantees the efficiency of flotation process and increase quality rate of enrichment.
The purpose of this work is to improve the reliability of devices for the detection of metal impurities in the production line of technological raw materials using eddy current self-sustained sensors. An effective way to increase their reliability is to increase the ratio between useful signal and background noise in the conversion signal channel of the device. This ratio can be increased by developing an optimal device structure. The device structure is designed using the method of optimal matched filtering of signals from background noise.
