The Method of Reagent Control Based on Time Series Distribution

Due to the distribution of bubble size changes with the reagent dosage in a flotation process, a dosage control method based on time series distribution of bubble size during the gold‐antimony flotation process is proposed. Firstly, since the flotation conditions cannot be described fully by the features of a single froth image, the concept Using the basic dosage pre-setting model based on RIMER and feedback reagent addition compensation model based on RBR, we implemented an automatic optimal-setting control for the gold-antimony flotation process and tested it in the froth image monitoring system of a gold-antimony flotation plant in Hunan province, China, Two-Step Optimal-Setting Control for Reagent Addition in Froth

Design of Soft Sensor for Industrial Antimony Flotation Based on

1 Excerpt. A deep convolutional neural network (CNN) is used to design an online antimony flotation process detection system, instead of traditional artificial observation or on-stream analyzers (OSA), that is used for real-time detection of froth grade and abnormal condition. Froth flotation is the most widely used method of mineral Therefore, it is desirable to develop machine vision-based systems to automatically monitor the operating conditions [7]. In the froth flotation, as the froth appearance status has a close relationship with the operating conditions, some visual features of froth appearances, such as texture [8,9], flow velocity [10,11], mineral Visual information model based predictor for froth speed control

Reagent Dosage Control for the Antimony Flotation Process

A reagent dosage hybrid control strategy for the antimony flotation process is proposed in this work. This strategy consists of two parts: reagent dosage tracking control based on a froth size probability density function (PDF) and reagent dosage compensation control based on a distributed-machine vision predictive model. The proposed method Froth flotation is a crucial step in sulfide precipitation flotation, and it is a commonly used technology to selectively separate target metals from sulfide precipitation under the action of collectors (Ma, 2012, Mikhlin et al., 2016, Wang et al., 2016, Wills and Finch, 2016, Ye et al., 2017, Feng et al., 2018).Flotation and adsorption mechanism studies of antimony sulfide
