In the antimony flotation plant, our research team had established the measurement and monitoring platform. An industrial RGB camera was used to record the froth appearance video. The videos were delivered to an industrial computer through optical fiber, and then were processed and analyzed. The operators monitor the process using …
Machine vision is widely used in the monitoring of froth flotation plants as a means to assist control operators on the plant. While these systems have a mature ability to analyse physical froth features, such as the colour of the froth and bubble size distributions, research has continued to focus on their use in automated control systems, …
Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …

Then a model predictive control is applied to validate the proposed froth image feature in section 5. Section 6 concludes this paper. 2. ANTIMONY FLOTATION PROCESS DESCRIPTION In this paper, a real gold-antimony flotation plant located in Hunan, China is discussed. The focus of the discussion is the antimony flotation …
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 …

In 2004 the main dressing plant in Klichka was reconstructed and started for fluorspar flotation. In 2014 Voyager Group has started a new history of the plant. Dressing plant consists of two flotation lines and one gravity line. Currently it processes antimony ores and produces antimony flotation concentrate with Sb content 50% min.
The antimony flotation plant in our case is manipulated by operators. Through observing the froth in the rougher bank, the operators adjust the reagent dosages. The concentrate grade is offline assayed every 2 h, which is a time-delay feedback information. The operators will correct their adjustment behavior according to the …
Halıkoy Antimony Plant. Halikoy Antimony Plant is in southeast İzmir. Its underground mine is in the Emirli village of Odemis district whereas its ore enrichment plant (flotation plant) is in Beydag – Halikoy. Emirli Antimony Mine …
Preferential flotation of antimony before gold is being used in a Sb-Au plant in Qinghai province.Because of high oxidation and severe argillation,gold concentrate grade and the recovery rate are very low.In order to enhance the recovery of gold,CIL gold extraction test is carried out on antimony flotation tailings,with gold leaching rate reaching …
The proposed method was applied in a gold-antimony flotation plant located in Hunan, China. It improved the efficiency of froth flotation and reduced false reagent operation. This article is ...
