Antimony is a chemical element with the symbol Sb and atomic number 51. It is a silvery-white metalloid with a bluish tint. As a metalloid, antimony is used as an alloying additive to improve hardness, mechanical strength, and thermal and electrical conductivity of alloys. Lead-antimony alloys are used in the manufacture of plates for lead-acid batteries.
The applications of antimony include:- Storage batteries
- Antifriction alloys
- Printing alloys
- Small arms and tracer bullets
- Cable sheathing
- Matches
- Pharmaceuticals, including antiprotozoal agents
- Soldering (some lead-free solders contain up to 5% Sb)
- Use in linotype printing machines
In its finished form, antimony is used in the production of refractory compounds, ceramic enamels, glass, paints, and ceramic products; in the manufacture of paints, varnishes, glass, pottery, and pharmaceuticals; as a corrosion-resistant material in household equipment; and in the production of pipes for transporting acids and other aggressive liquids.
Antimony is increasingly used in the semiconductor industry for the production of diodes, infrared detectors, and Hall-effect devices.
General information and reserves:The deposit is located in the Republic of Tajikistan, Sughd region. A designated land plot is available at an altitude of 1,600 meters above sea level. The area is economically developed, supplied with electricity, and accessible by road; the deposit is located 3 km from the main asphalt road. Water supply is provided by a nearby river and springs.
The site consists of several fields, with the main one having been explored during the Soviet period. The following reserve estimates are based on those data:
- Category C1: Ore – 694 thousand tons; Antimony – 21.776 thousand tons
- Category C2: Ore – 363 thousand tons; Antimony – 8.126 thousand tons
In 2023, an иностранной компанией conducted exploration activities, which identified larger reserves of antimony (over 1 million tons) and other precious metals within the area.
Technological characteristics:Tests were carried out using flotation and gravity separation methods. The best results were obtained using the flotation process: an antimony concentrate with 42% Sb content was achieved, with a recovery rate of 72.9%.
The development and extraction of the main part of the deposit is planned to be carried out by open-pit mining.
