Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
A process for the production of antimony trioxide comprising the steps of: (i) reacting antimony trisulfide with iron (III) chloride to produce antimony trichloride; and (ii) hydrolyzing antimony trichloride to produce antimony trioxide. In a preferred embodiment, the process is substantially closed or near-closed loop. Antimony trioxide is a known flame retardant for use in plastics, ceramics ...

After multi scheme of test, Xinhai finally decided to use gravity separation-flotation process to recycle the antimony ore, and in the test the grade of antimony is 58.71%, the recovery rate of mixed antimony concentrate Is 93.75%. xinhai achieved the maximum intensity of the recovery of the antimony ore, which reduced the environmental ...
Feb 01, 2021· Understanding the roasting process is the key to obtain antimony oxide and metallic antimony from stibnite concentrate. Therefore, the microwave heating mechanism of stibnite concentrate in the roasting process was studied and the schematic diagram of this process …
Antimony concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also …
Jun 28, 2021· Preliminary indications are that the sulfide concentrate produced by Perpetua would probably not be feasible as a source of antimony trisulfide but would be ideal feedstock for processing into antimony metal and oxide at the Company's smelter in Mexico. Forward Looking Statements:
process as non-toxic, easily-buried and/or utilizable compounds. The objective of the present paper is an investigation of arsenic, antimony and non-ferrous metals distribution during converter slag sulfiding depletion by a sour cop-per-zinc concentrate as applied to conditions of semi-products and reverts of the lead industry treatment.
Jan 01, 1989· However, this process ran into difficulties and was not put on steam. The quality of the antimony concentrate can be seen from the figures in Table 3. Antimony recovery is low, about 60%, probably due to the heavy dosage of cyanide in the upstream gold leaching process. Dissolved antimony contributed to the high reagent consumption.
