1. Antimony – general aspects. Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3. 121 Sb (57.21% abundance) and 123 Sb (42.7% abundance) are the two stable isotopes of antimony. Antimony can possess different oxidation states (such as +5, +3, 0, −3 and …

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 ...
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of …
For the problem of reagent addition control in antimony rougher flotation, belief rule base (BRB) method can be adopted to express the human knowledge and to address the uncertainty in the ...

This method, characterized by its minimal direct attachment to the ground, allows the slab to 'float' above the soil, leveraging specific construction techniques to adapt to site conditions effectively. Here, we'll delve into the aspects that make floating slabs unique, including their construction process, the critical role of soil ...
The diversification of ore sources in a copper flotation process often causes difficulty in indentifying the flotation conditions as well as the instability of the production process.
This paper describes a method based on machine vision system to classify different grades of Antimony during the floatation process. It is proved that the size of bubbles provides …
Antimony (Sb) is a chemical element of the periodic table, located in the group 15 and the period 5, and is having the atomic number 51. It is a hard, ...

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 …
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 …
A Raman spectroscopic system is designed to collect Raman spectra of the froth layer during the antimony flotation process.. We constructed a quantitative concentrate grade quantification model based on Raman spectra of mixed minerals in froth layers..

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 …
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
