Especially for sulfide antimony ores, the most common beneficiation method is flotation. Therefore, antimony ore consisting of stibnite mineral obtained from Tokat-Turkey region was used in this study. Due to the low antimony (5.06%Sb) and the high Arsenic (1.38%As) content, it is an important requirement to increase the Sb content of this ore ...
Reagent addition during antimony rougher flotation in a gold-antimony flotation plant was used to verify the reagent addition optimal-setting control method. A total of 530 groups of industrial process data, including feed conditions, froth features, reagent dosage, and other process data, were continuously collected from the plant.
the underflow of antimony-scavenging bankI enters antimony-scavenging bankII. The underflow of this bank is the final tailing of the whole flotation process, namely mixed tailings of gold and antimony. The froth overflows from antimony-scavenging bankI and antimony-scavenging bank II will be fed into the antimony-roughing bank for
The method for froth floatation condition recognition based on adaptive feature weighted
1. FLOTATION PROCESS ANALYSES 1.1. Antimony Flotation Process Description Froth flotation is an important method to separate valuable minerals from ore by taking advantage of the physical-chemical properties of mineral surfaces [2]. This paper concentrates on a gold-antimony flotation process in China.
A kind of sulfur oxygen symbiosis mixing antimony ore flotation recovery method, comprise the following steps and regime of agent: use sodium hexameta phosphate to make mineral dispersant, potassium permanganate makees mineral oxide agent, sodium sulfide makees mineral vulcanizing agent, copper sulfate makees the activator of mineral, butyl xanthate …
Flotation is one of the main methods for separating antimony minerals; The flotation method has a significant effect on the treatment of sulfide minerals such as antimony, but it is …
The froth layer, enriched in antimony, is scraped from the antimony-roughing bank and then sent to antimony-cleaning banks. The overflows of antimony-cleaning bank II are gathered to produce the antimony concentrate. And the underflows of antimony- cleaning bank I and II need to be transport to antimony-roughing bank for re-flotation.
A new method of flotation dose matching is proposed based on rough sets and case-based reasoning., realized the control of reagent adding in floatation process. This method has been applied in a real industrial site. The application results show that the proposed method can effectively reduce the contents of tailings and improve the recovery rate.
The proposed FS method, mRMR-BSTA, is applied into the production condition recognition of gold-antimony froth flotation to reduce the redundancy and noise of the extracted 38 features. 5 efficient features are selected and the production condition recognition of gold-antimony froth flotation is categorized into 8 classes with high ...
Methods of flotation may be classified for purposes of study into three varieties, on the basis of the force that acts to buoy the mineral of metallic luster, as: skin-flotation methods, oil-flotation methods, froth-flotation methods. Skin-flotation.

Antimony is a strategic metal which is used in many industrial areas. The content of the antimony ore is the most important point for determining the area of usage.
The antimony ore beneficiation methods mainly include manual separation, gravity separation, flotation, and other methods. Select the beneficiation process of a specific ore based on the physical and chemical properties of the ore type …
In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.
bulk flotation of antimony ore. Bulk flotation is a method where all sulphide minerals are floated together. They are then separated into valuable minerals and gangue minerals in the subsequent steps.
The invention relates to a novel flotation method of lead-antimony-zinc sulphide ores, particularly for selecting low-grade complex refractory lead-antimony-zinc sulphide ores. A method of ore selecting and washing is adopted, which combines washing and selection and eliminates interference of unfavorable factors such as harmful ions, drugs, slurry and the like on the …
