Antimony (Sb) has received increasing environmental concerns due to its potential toxic and carcinogenic properties. In the present work, the electrocoagulation technique was used to treat the flotation wastewater from a heavy antimony polluted area, and the mechanism of removing Sb was also investigated.

The results show that it is impractical to remove arsenic (As) and antimony (Sb) from downstream processes by using selective flotation. It was observed that 22% of total Sb and 31.1% of As remained in the final tailings. ... The bulk flotation method as a pre-treating method resulted in the concentrate with less toxic chemical elements such as ...

Antimony flotation is a complicated industrial process with an unknown system structure. Manual manipulation is still widely used by observing the froth appearance, which relies on operators' experience. ... Liu et al. [10] proposed a novel multiresolutional multivariate image analysis method for the monitoring of flotation processes. This ...

and flotation methods were applied. Different flotation flowsheets were performed for considering the number of stages and also parameters such as feed size, collector dosage and activator type.

Usage: Flotation is a commonly used method for antimony ore dressing and is suitable for various ore types, including sulfide antimony ore, sulfide-oxide mixed antimony ore, stibnite, tungsten ...

The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.

Froth flotation is the most widely used method of mineral separation. The froth state reflects the information of mineral content in the froth. Therefore, the most common method is to evaluate the froth surface state to control the operation to improve the mineral recovery. However, it is still a challenge to evaluate the froth state in real time, efficiently, quickly and accurately. This ...

One of these examples is an operation in Canada, where a dithiophosphate has been used as the only collector in the flotation of an ore containing stibnite and arsenic-bearing minerals, the latter ...

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. Since, high-grade antimony ores ...

Highlights. •. Froth flotation plays a key role in the recovery of stibnite from primary and secondary sources. •. A critical literature review on stibnite flotation had not been …

Sometimes, even if it can not directly select qualified antimony concentrate, it is often selected as a pre-selection operation for antimony flotation operations. Especially when flotation has many difficulties in …

The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes …

Antimony ore flotation is the most important dressing method for antimony ore. Antimony sulfide minerals are easy to float minerals, and most of them use flotation to improve the grade of antimony ...

Among these methods, fuzzy logic control (FLC) is an efficient control technique which not requires the mathematical model [13]. The operators' experience, expert knowledge, and industrial data can be fully utilized in the FLC. ... And considering gold-antimony flotation is a preferential fraction-mixed flotation process which includes the ...

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 ...

Introduce Antimony Ore Beneficiation. Antimony ore beneficiation method is mainly gravity beneficiation method and flotation method. The flotation method is applied to the fine-grained dipping antimony sulfide ore, the antimony ore with low original grade is difficult to profit from direct flotation, and must be enriched by gravity beneficiation method and then flotation, or …

It is a method of flotation separation of antimony gold (arsenic) by using ammonium butyrate black, which has strong collecting ability and good selectivity for stibnite, but weak collecting ability for arsenopyrite and pyrite. First, coarse-grained monomer natural gold is immediately selected in the grinding classification circuit with a gold ...

Gravity separation is a widely used method for antimony concentration. It exploits the difference in density between the antimony minerals and the gangue (non-valuable minerals) to achieve separation. ... Air is then introduced into the flotation cell, causing the antimony minerals to float to the surface as a froth, while the gangue particles ...

Flotation is applied to fine-grained disseminated antimony sulfide ore. It has high beneficiation index and recovery rate. The commonly used single flotation method is suitable for processing single antimony ore. The combined gravity separation-flotation method is suitable for treating antimony ore with uneven particle size. For example ...

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 …

The enrichment of antimony ore to increase its quality is achieved through various methods, including positive flotation, reverse flotation, bulk flotation, and preferential flotation. antimony ore

A flotation method of arsenic-containing gold-antimony symbiotic ore comprises the steps of dissociating the ore to obtain a selected ore pulp, and then carrying out an equal floatable process on the selected ore pulp to obtain antimony gold concentrate and gold-antimony concentrate; the flotation reagent used in the roughing I of the floatable process comprises sodium carbonate.

The invention discloses a flotation separation method of antimony sulfide and gold-bearing pyrite. Sodium hexametaphosphate is adopted as a dispersing agent, sodium silicate is used as a silicon and calcium gangue inhibitor, copper sulfate is used as an antimony and gold mineral activating agent, butyl xanthate is used as a collecting agent, and No. 2 oil is used as a …
