Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength. A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in presses), ammunitions and cable sheathing.
Flotation is the main beneficiation method for obtaining powdered antimony concentrate, and flotation is included in almost all beneficiation processes. The types of ores used for processing are: mono-antimony sulfide ore, sulfide-oxidized mixed antimony ore, tungsten antimony gold polymetallic sulfide ore, antimony arsenic gold sulfide ore ...
Antimony ore concentrate (principally trisulfide, also called stibnite in less amounts, as well as oxides such as valentinite, senarmontite, and cervantite) was examined in one inhalation study, as was antimony trichloride .

The antimony that produces gold and silver is called precious antimony. (4) Vortex volatilization melting of antimony sulfide concentrate in cyclone furnace. Iron oxide ore, limestone, quartz quartizile, and charcoal are pulverized and then mixed with antimony sulfide concentrate. The mixture is added into the vortex furnace for volatilization ...
Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association …
Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity antimony. The natural sulfide of antimony was known and used in Biblical …
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 …
A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented. The influences of molten salt addition and composition, ferric oxide dosage, smelting temperature and duration on extraction efficiency of …
Antimony is not an abundant element but is found in small quantities in over 100 mineral species. It is most often found as antimony(III) sulfide. It is extracted by roasting the …
Antimony–gold concentrate is a refractory gold ore, and the direct cyanide leaching efficiency is very low [].For antimony–gold concentrate with high antimony content (Sb > 30%), the volatilization melting of blast furnace and reduction melting of reverberation furnace is generally adopted at present, and the gold is finally enriched in noble …
Antimony (Sb) is one of the most commonly used metallic element, with global reserve of 1.9 million tons. According to recent report, almost 80% of Sb …
The anodic reaction mechanism of the complicated antimony lead concentrate in slurry electrolysis is investigated by the anodic polarization curves determining under various conditions and the mineralogy study of the slurry electrolysis residue The direct leaching rate of the antimony acid dissolution is up to 35% by means of the oxidation reaction of …

In 2018, the Olimpiada mine entered the antimony supply chain with an output of 23.6kt Sb – instantly becoming the world's largest source of antimony concentrates. The concentrate from Olimpiada required antimony smelters in China to adapt their flow sheets to account for the higher gold and lower antimony grades compared to other …
In 2021, the global antimony ore and concentrate market was finally on the rise to reach $2.3B for the first time since 2018, thus ending a two-year declining trend. Over the period under review ...

The concentrate grade in the antimony flotation process will be continuously predicted based on the proposed method. Based on our method, the prediction of concentrate grade is based on combining the Raman spectrum measured at the current moment T with the Raman spectrum measured over the last T-1 steps.

The massive antimony concentrate tungsten obtained by manual separation contains more than 7% antimony, which can then be smelted to produce raw antimony. It should be noted that in order to improve the efficiency of manual separation, the ore should be washed to remove sludge impurities before beneficiation. The hand-selected tailings …
What is Antimony Concentrate? Antimony xide is formed when antimony is burnt in air. In the gas phase, the molecule of the compound is Sb 4 O 6, but it polymerizes upon condensing. Antimony pentoxide (Sb 4 O 10) can be formed only by oxidation with concentrated nitric acid.
