Flotation is another commonly employed technique in antimony concentration. It relies on the selective attachment of chemicals to the antimony minerals, enabling their separation from the gangue. The flotation process …
Fig. 1 shows the typical diagram of gold–antimony flotation process. Rougher flotation is the first step of flotation after the gold–antimony ore is ground, mixed with water and classified. Rougher flotation products include the rougher froth and the pulp, and the froth is located above the pulp in the rougher flotation cell.
Using flotation cells offers several advantages, such as the ability to handle a wide range of feed sizes and ore types, can be adjusted and optimized by changing operating parameters, achieve high throughput and recovery, and good selectivity and separation efficiency.In addition, they are relatively simple to operate and maintain. On the other hand, …

They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to keep the solids particles in suspension in the pulp. A flotation cell is an appliance in which froth ...
Results of single-mineral and mixed-mineral flotation tests consistently show that BYYS can effectively achieve the selective separation of poisonous sand and antimony arsenic.
Mechanical flotation machines are further divided into three subcategories: Self-aerating cells: These cells rely on the suction created by the impeller to draw in air and disperse it into the slurry. Forced-air cells: Pressurized air is directly supplied to the cell, providing a more uniform bubble distribution.

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 was tested on a gold …
A bulk sulfur concentrate with 24.54% Sb and 3.69% As content obtained as a result of the rougher flotation was obtained with a recovery of 98.9%. This product was subjected to 6 stages of cleaning flotation and a concentrate with a content of 63.8% Sb and 0.31% As was produced with an antimony recovery of 83% Sb.
Fig. 1 shows that the antimony flotation process includes 5 parts: roughing, scavenging Ⅰ, scavenging Ⅱ, cleaning Ⅰ, and cleaning Ⅱ, respectively. In the roughing cell, the input pulp mainly comes from the output pulp of the gold roughing cell. Combined with the flotation reagents, most of the antimony ore particles are
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were …
