A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column to overflow …

When choosing a separation method for antimony ores, it is necessary to consider the physical and chemical properties such as ore type, mineral structure and composition, and also consider the content of valuable components in the ore and the economic benefits of mineral processing. The antimony ore beneficiation methods …
Relationship between antimony content (%) in flotation feed and antimony recovery (%) and grade (%) in the final flotation concentrate for selected industrial and bench-scale studies on froth flotation of stibnite-bearing ores around the world.
At the plant of the Consolidated Murchison Co. in the Transvaal, South Africa, where a refractory high-antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery amounted to ...

Antimonite ore is processed by hand-picking–flotation or heavy medium separation–flotation to pick out lump ore, rich lump ore, and concentrate that will go into the smelting process. Antimony smelting is done through the pyrometallurgical process or the hydrometallurgical process, but mostly the pyrometallurgical process.
The aim of this study is to determine the optimum conditions for flotation of antimony ore in terms of Sb and As content of concentrate. And also decreasing Sb content while increasing the As ...
The gold-antimony froth flotation in this study adopts a part priority-mixed flotation process, meaning gold flotation is performed in alkaline pulp, followed by …
The design of flotation circuits for beneficiation of stibnite is usually very straightforward: rougher, scavenger and two-stage cleaner flotation are usually enough …

Hence, new techniques in the fields of design, modelling, optimization, and control of flotation processes have attracted a great deal of attention. This Special Issue is dedicated to the latest findings on methodologies, applications, and case studies in the field of the flotation to improve process efficiency, reduce energy consumption, and ...
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 …

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 (natural type and industrial type), mineral composition, structural structure, and process particle size of useful minerals.
The innovation of this study relies on the construction of a hybrid flotation column that generates in situ microbubbles, by employing electrolysis of water, and the …
Mineral ore beneficiation and value addition has become a key factor for economic growth in Africa. Froth flotation process is used to concentrate relatively low grade ores.

Some progress using combined processes has been made through the introduction of sulfide flo-
The froth flotation technique can be considered one of the most efficient methods for the separation of minerals. Prior to utilizing any physicochemical separation method, the size of the mined ore must be decreased to facilitate the release of the valuable materials. This practice, along with the increased exploitation of ores that carry …
The largest Russian antimony ore deposits are reviewed analytically. The present-day physicochemical methods (nuclear quadrupole resonance, X-ray electron spectroscopy, multinuclear (13C, 15N, 31P) NMR) are used to develop innovative technologies.
